Good. No nameservers allow recursive queries.
Cloudflare’s DNS uses a global network to speed up responses. Normally, the IP addresses at the parent nameservers and Cloudflare’s servers should match. If they don’t, it might just be a short-term update.
Cloudflare manages glue records through their global DNS infrastructure.
Good. The NS records at all your nameservers are identical.
Good. All nameservers listed at the parent server responded.
All NS records appear to be valid hostnames.
You have 2 nameservers. This meets the minimum requirement, though RFC2182 section 5 recommends at least 3 for better reliability.
Good. All nameservers are answering authoritatively for your domain.
Good. All NS records match between parent and nameservers, as required by RFC1034 section 3.6.
Good. All parent-listed nameservers are reported by your nameservers, as required by RFC1034 section 3.6.
Good. No CNAME records found for NS records, as per RFC1912 section 2.4 and RFC2181 section 10.3.
Anycast provider detected (Cloudflare).While 3 IP pair(s) share a
/16
prefix, Cloudflare distributes these across globally diverse datacenters using anycast routing. No subnet diversity concern per RFC2182 section 5.| Status | Test name | Information |
