How this service works
Is the domain's DNS hosted by rackspace? Looks up the NS records (Cloudflare DoH) and matches them against rackspace's nameserver patterns, returning yes/no, the nameservers and which ones matched. Vendor detection for sales, migration and security work. $0.01 per lookup.
Output
Returns a boolean yes/no indicating whether the domain's DNS is hosted by Rackspace, the full list of NS records retrieved via Cloudflare DoH, and a subset showing which specific nameservers matched Rackspace's known nameserver patterns.
Example use cases
Pre-sales Rackspace customer targeting
“I'm building a prospect list and want to know if techfirm.io is currently using Rackspace for DNS hosting — can you check their nameservers and tell me whether Rackspace comes up as a match?”
DNS migration readiness check
“Before we kick off the migration project for clientbrand.com, can you confirm whether their DNS is currently sitting on Rackspace? I need the actual nameservers and which ones matched.”
Security audit for DNS vendor exposure
“Run a check on startupxyz.com to see if their DNS is hosted by Rackspace — we're auditing third-party DNS dependencies across our portfolio and need a yes or no plus the nameservers.”
Technical details
Endpoint
GEThttps://dns.intel.rallylive.ca/dns/hosted-by/rackspace?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically determine whether a specific domain's authoritative DNS is managed through Rackspace, particularly for sales prospecting, migration planning, or DNS vendor auditing. It is purpose-built for Rackspace detection using Cloudflare DoH for reliable NS resolution, making it preferable to generic NS lookup tools when Rackspace-specific pattern matching is required.
Side effects
- Domain does not exist or has no NS records — returns no match with empty nameserver list
- Cloudflare DoH unavailable — lookup fails with a connectivity or timeout error
- Malformed domain input — request rejected or returns an error
- Domain uses Rackspace nameservers not yet in the pattern list — false negative
