Dear DNS-Operations Community,

I’m reaching out on behalf of Real Estate Domains LLC, the registry operator for the .realtor™ top-level domain, regarding an issue we’re encountering with name resolution on certain .realtor™ domains—specifically failures when using OpenDNS (Cisco Umbrella) resolvers.

Over the past week, we’ve received multiple reports from customers indicating that some .realtor™ domains (for example, hlaor.realtor) are failing to resolve through OpenDNS, while resolving normally across most other major recursive resolvers, including Google Public DNS, Cloudflare, and Quad9.

Our technical team, along with our registry services provider (Nominet), has confirmed that:

  *   The registry and authoritative name servers are correctly configured and responding consistently.
  *   DNSSEC is not enabled for these domains.
  *   The issue appears limited to specific recursive resolvers within OpenDNS, suggesting a potential caching or validation inconsistency.

Unfortunately, we have been unable to locate a direct escalation path or contact within Cisco/OpenDNS for this type of resolver-level issue. We’re therefore seeking guidance from this community to:

  1.  Identify anyone at Cisco/OpenDNS who could assist in reviewing their resolver behavior for the .realtor™ TLD; or
  2.  Recommend any next steps we can take to ensure resolution of this issue as quickly as possible.

Thank you in advance for any advice or introductions you can provide.
I greatly appreciate this community’s expertise and collaboration.

Best regards,
Matthew Embrescia
President & CEO
