IDX Broker documents a CNAME connection, account configuration, and a separate HTTPS control. [Custom domain setup](https://support.idxbroker.com/hc/en-us/articles/34490030166555-Setting-Up-a-Custom-Domain), [HTTPS setup](https://support.idxbroker.com/hc/en-us/articles/34489904938011-Enable-HTTPS-or-SSL-on-Your-IDX-Site). Checked: 2026.10.22. For a real estate agent, acceptance should include opening property search from the main website and reaching the intended inquiry recipient. A saved DNS record alone does not demonstrate that route. The checks below are a proposed provider brief. ## What does a custom IDX subdomain change? It gives your hosted IDX pages an address beneath your own domain. IDX Broker's setup guide describes this arrangement. [Custom domain setup](https://support.idxbroker.com/hc/en-us/articles/34490030166555-Setting-Up-a-Custom-Domain). Checked: 2026.10.22. Ask the provider to record the current search address and intended replacement. Keep the main website address beside them so everyone can identify which hostname changes. ## Who should control the domain account? Keep the account under the business owner's control and give the provider the access needed for the agreed work. Record who can edit DNS and who can recover access. This is an ownership recommendation. Confirm the actual account holder before scheduling changes or relying on an old handover document. ## Is this a new setup or a domain change? Identify that distinction before editing. IDX Broker's change guide requires domain-change requests through its MLS team, rather than self-service changes to an existing account relationship. [Domain change process](https://support.idxbroker.com/support/s/article/changing-brokerage-or-domain). Checked: 2026.10.22. Ask support which route applies when your existing custom hostname is being replaced. Retain its reply with the implementation brief. ## Which DNS record does IDX Broker document? The vendor specifies a CNAME pointing to `subdomains.idxbroker.com`. It warns against substituting a fixed IP address in an A record. [CNAME target and record type](https://support.idxbroker.com/hc/en-us/articles/34490030166555-Setting-Up-a-Custom-Domain). Checked: 2026.10.22. Have the DNS provider confirm the hostname field format for its interface. Record the proposed entry before saving it. ## Should you replace the homepage hostname? Prefer a separate search hostname unless the provider has reviewed the homepage implications. IDX Broker warns that choosing `www` requires checking continued homepage operation. [Hostname considerations](https://support.idxbroker.com/hc/en-us/articles/34490030166555-Setting-Up-a-Custom-Domain). Checked: 2026.10.22. Ask the provider to identify any existing service attached to the chosen name. Resolve a conflict before replacing its record. ## Should unrelated DNS records change? Keep the proposed change limited to the approved IDX hostname. Ask for an explicit reason before changing any other record. Save the affected record's prior value and the intended replacement. Have the provider name the restoration procedure and the person responsible for carrying it out. ## How long should you allow before account setup? IDX Broker recommends waiting one day between creating the CNAME and configuring the custom domain in its account. [Vendor sequencing recommendation](https://support.idxbroker.com/hc/en-us/articles/34490030166555-Setting-Up-a-Custom-Domain). Checked: 2026.10.22. Treat that as planning guidance. Ask the provider to verify the record's observed state before continuing. Do not promise visitors an exact completion time. ## Where is the custom domain configured? The documented initial setup uses **Account > Details**, then **Subdomain/Domain Control**, with **Use Custom Domain** enabled. [Account setup controls](https://support.idxbroker.com/hc/en-us/articles/34490030166555-Setting-Up-a-Custom-Domain). Checked: 2026.10.22. For an existing-domain replacement, follow the confirmed support process. Do not infer that an available field removes the need for account or MLS coordination. ## What proves the CNAME was accepted? Use the account's reported CNAME result as an intermediate check. The setup guide describes error and success messages beside the custom-domain field. [CNAME validation messages](https://support.idxbroker.com/hc/en-us/articles/34490030166555-Setting-Up-a-Custom-Domain). Checked: 2026.10.22. Retain the result without exposing credentials. Continue with HTTPS and public-page checks before accepting the work. ## Does the main website certificate cover IDX setup? Complete the IDX Broker HTTPS step separately. Its guide directs the account holder to **Account > Details > Enable HTTPS**. [IDX HTTPS control](https://support.idxbroker.com/hc/en-us/articles/34489904938011-Enable-HTTPS-or-SSL-on-Your-IDX-Site). Checked: 2026.10.22. Require the provider to demonstrate the intended search hostname over HTTPS. Record any browser warning as an unresolved fault. ## What confirms certificate creation? Look for the vendor's completion message and then inspect the public destination. IDX Broker distinguishes successful initiation from confirmation that a custom-domain certificate has been procured. [Certificate status](https://support.idxbroker.com/hc/en-us/articles/34489904938011-Enable-HTTPS-or-SSL-on-Your-IDX-Site). Checked: 2026.10.22. Ask the provider to preserve the outcome and date. Leave the certificate check open if only the initiation message is available. ## Should you toggle HTTPS while troubleshooting? Agree the recovery sequence with support before disabling it. IDX Broker documents a 24-hour delay before SSL can be enabled again after disabling it. [SSL reactivation restriction](https://support.idxbroker.com/hc/en-us/articles/34489904938011-Enable-HTTPS-or-SSL-on-Your-IDX-Site). Checked: 2026.10.22. Use a recorded diagnosis to choose the repair. Repeated toggling is a poor substitute for understanding the reported error. ## Can HTTPS pages still show asset warnings? Yes. The vendor notes that MLS images may cause mixed-content warnings when they are not served over HTTPS. [MLS image consideration](https://support.idxbroker.com/hc/en-us/articles/34489904938011-Enable-HTTPS-or-SSL-on-Your-IDX-Site). Checked: 2026.10.22. Have the provider identify the exact asset and responsible service. Do not accept a warning without a named resolution or documented limitation. ## Which website links need review? Inventory navigation, search buttons, embedded widgets, and wrapper links. IDX Broker instructs customers to update existing IDX links after switching the custom subdomain. [Post-switch link updates](https://support.idxbroker.com/hc/en-us/articles/34490030166555-Setting-Up-a-Custom-Domain). Checked: 2026.10.22. Compare each destination with the approved search address. Check the visible page instead of treating a text replacement count as acceptance. ## Do domain changes affect wrapper URLs? Review them during the same change. IDX Broker's domain-change guide calls for updating the global wrapper and checking category and page overrides. [Wrapper review after a domain change](https://support.idxbroker.com/support/s/article/changing-brokerage-or-domain). Checked: 2026.10.22. Keep wrapper repair separate from DNS repair in the issue list. The provider should identify which observation each change addresses. ## What should the buyer journey check contain? Start on the main website, enter property search, open a listing, and return to the service pages. Record the destination at each transition. Repeat using a phone and a desktop. Ask the reviewer to note broken navigation, unexpected hostnames, unreadable controls, and warnings that interrupt the task. ## How should inquiry delivery be accepted? Agree a marked test with the intended recipient and use contact details you control. Ask a property-specific question through the agreed route. Compare the received message with the submitted details. Keep the check open if the recipient, property reference, or reply information is missing. ## What about seller-service forms? Check them independently when their route belongs to the project scope. Keep a seller-service form's result separate from the property-search inquiry result. Record the starting page, expected recipient, submitted test, and matching receipt. This prevents a successful search demonstration from standing in for unrelated contact work. ## Does the custom address guarantee search visibility? No visibility result is established by this configuration guide. IDX Broker cautions that HTTPS does not replace content quality and SEO best practices. [HTTPS and SEO limits](https://support.idxbroker.com/hc/en-us/articles/34489904938011-Enable-HTTPS-or-SSL-on-Your-IDX-Site). Checked: 2026.10.22. Keep indexing observations, search positions, visits, and received inquiries as separate records. Attribute changes only when the evidence supports the connection. ## What should remain unresolved before release? Keep unknown account requirements, failed certificate checks, incorrect links, and missing inquiry receipts on the open-work list. Name the person responsible for each item. Ask support to resolve any conflict between the initial-setup guide and your account's change process. The account-specific answer is UNRESOLVED until confirmed. ## What should the handoff preserve? Retain the approved hostname, record change, support instructions, certificate outcome, updated-link list, and acceptance results. Keep credentials in the authorized account system. Include the provider's recovery instructions and the limits of the completed work. Distinguish documentation reviewed from tasks demonstrated on your website. ## How do you brief the website repair? Bring the current website, intended search hostname, observed faults, and required acceptance evidence to the [real estate website scope](/for/real-estate). If WordPress integration is also in question, use the [IDX Broker plugin checklist](/articles/idx-broker-wordpress-plugin-setup) for that separate brief. Agree who owns DNS, IDX support, website links, and received-inquiry checks before work begins. - [Find and manage an IDX Broker API key for your real estate website](/articles/idx-broker-api-key-location) - [IDX Broker dynamic wrappers for real estate agent websites](/articles/idx-broker-dynamic-wrapper) - [IDX Broker forced registration: choose and test the browsing gate](/articles/idx-broker-forced-registration) ## Related: Real estate - [Find and manage an IDX Broker API key for your real estate website](/articles/idx-broker-api-key-location) - [IDX Broker dynamic wrappers for real estate agent websites](/articles/idx-broker-dynamic-wrapper) - [IDX Broker forced registration: choose and test the browsing gate](/articles/idx-broker-forced-registration) ---- ```text .|########||. .|########||. .|########||. |##||. .||##|. |##||. .||##|. |##||. .||##|. |#|. .|#|. |#|. .|#|. |#|. .|#|. |#| |#| |#| |#| |#| |#| .#| |#. .#| |#. .#| |#. .#. .#| .#. .#| .#. .#| |#. .#| |#. .#| |#. .#| |# ...... #| |# ...... #| |# ...... #| .# ||#########| #| .# ||#########| #| .# ||#########| #| .#. |######||######|. .#. .#. |######||######|. .#. .#. |######||######|. .#. #. .##|###|##|#|######| .# #. .##|###|##|#|######| .# #. .##|###|##|#|######| .# || |##|#||||||||||||#||#| || || |##|#||||||||||||#||#| || || |##|#||||||||||||#||#| || # |#||||||||||||||||||||#| #. # |#||||||||||||||||||||#| #. # |#||||||||||||||||||||#| #. || |#||||||||||||||||||||||#| || || |#||||||||||||||||||||||#| || || |#||||||||||||||||||||||#| || # .#||||||||||||||||||||||||#| # # .#||||||||||||||||||||||||#| # # .#||||||||||||||||||||||||#| # || ....|||#||||||##|#|||#|#||##||||....|. || || ....|||#||||||##|#|||#|#||##||||....|. || || ....|||#||||||##|#|||#|#||##||||....|. || #. . ....|# ....#||| ||| .#||| ....#. .# #. . ....|# ....#||| ||| .#||| ....#. .# #. . ....|# ....#||| ||| .#||| ....#. .# # . ||||#| .#####|| . .#| .#||| ||||# #. # . ||||#| .#####|| . .#| .#||| ||||# #. # . ||||#| .#####|| . .#| .#||| ||||# #. .| ||||| #. |#|||||. || #. |#||. .||||| || .| ||||| #. |#|||||. || #. |#||. .||||| || .| ||||| #. |#|||||. || #. |#||. .||||| || || |.... #. ....|#. |. ...|. ....|| || || |.... #. ....|#. |. ...|. ....|| || || |.... #. ....|#. |. ...|. ....|| || #. .||||||##||||||##||####|||||||#||||||#| .# #. .||||||##||||||##||####|||||||#||||||#| .# #. .||||||##||||||##||####|||||||#||||||#| .# # .||####|###########################|. # # .||####|###########################|. # # .||####|###########################|. # # .#||||||.#.|| # |. ..# #| #|||||#| # # .#||||||.#.|| # |. ..# #| #|||||#| # # .#||||||.#.|| # |. ..# #| #|||||#| # # .#|||||| .. |# ## |#| ...#|#|||#| # # .#|||||| .. |# ## |#| ...#|#|||#| # # .#|||||| .. |# ## |#| ...#|#|||#| # # .#|||#|# .# .#| #| ##|.#..#|||||#| # # .#|||#|# .# .#| #| ##|.#..#|||||#| # # .#|||#|# .# .#| #| ##|.#..#|||||#| # # .#||||||############|######|||||#| # # .#||||||############|######|||||#| # # .#||||||############|######|||||#| # # |...||#||||||#||||#|#||||||#|||||#||| |.| # # |...||#||||||#||||#|#||||||#|||||#||| |.| # # |...||#||||||#||||#|#||||||#|||||#||| |.| # #. .. ||||# .|||##|. |#| .|| || .|||#. #| # .# #. .. ||||# .|||##|. |#| .|| || .|||#. #| # .# #. .. ||||# .|||##|. |#| .|| || .|||#. #| # .# || | ...|| ...##| | #| .|. |. ##### .. .| || || | ...|| ...##| | #| .|. |. ##### .. .| || || | ...|| ...##| | #| .|. |. ##### .. .| || || ||||| || ||||#| . |. |. |#. ||||| |#| || || || ||||| || ||||#| . |. |. |#. ||||| |#| || || || ||||| || ||||#| . |. |. |#. ||||| |#| || || .# |.....#|....|#.||||.|||##.|#|....||.#||.#. #. .# |.....#|....|#.||||.|||##.|#|....||.#||.#. #. .# |.....#|....|#.||||.|||##.|#|....||.#||.#. #. #.|||||||#############################| ||| .# #.|||||||#############################| ||| .# #.|||||||#############################| ||| .# || ##||#||#||||||#||#||#||#||##. || || ##||#||#||||||#||#||#||#||##. || || ##||#||#||||||#||#||#||#||##. || # .#|||||||||#||#|||||||||||#| # # .#|||||||||#||#|||||||||||#| # # .#|||||||||#||#|||||||||||#| # || |#||||||||||||||||||||||#| || || |#||||||||||||||||||||||#| || || |#||||||||||||||||||||||#| || .# |#||||||||||||||||||||#| #. .# |#||||||||||||||||||||#| #. .# |#||||||||||||||||||||#| #. || |#||||||||||||||||||#| || || |#||||||||||||||||||#| || || |#||||||||||||||||||#| || #. .######|#|#########| .# #. .######|#|#########| .# #. .######|#|#########| .# .#. |#####||||#####| .#. .#. |#####||||#####| .#. .#. |#####||||#####| .#. |# ||########|| #. |# ||########|| #. |# ||########|| #. |# ...... #| |# ...... #| |# ...... #| |#. .#| |#. .#| |#. .#| |#. .#. |#. .#. |#. .#. .#| |#. .#| |#. .#| |#. |#| |#| |#| |#| |#| |#| .|#|. .|#|. .|#|. .|#|. .|#|. .|#|. |##||. .||##| |##||. .||##| |##||. .||##| .||########||. .||########||. .||########||.
