Apologies if this is the wrong place, but I can’t really find much more information.
I’m having an issue where I can’t resolve a certain host “education.qld.gov.au” when using Cloudflare DNS (18.104.22.168)
I don’t have any issues with other websites or hostnames using that DNS, and when I tested on another internet connection suddenly it worked (Still with 22.214.171.124 configured)
I’m able to recreate the issue on multiple devices and confirm that on one internet connection 126.96.36.199 can resolve the host, on another internet connection 188.8.131.52 does not resolve the hostname.
Running public dns testing websites shows no issue with 184.108.40.206 resolving that hostname elsewhere in the world.
After a lot of searching the forums I learned that Cloudflare can be routing through different datacenter hosts depending on your location so I’m guessing it may be an issue with a certain location.
And NSLOOKUP results:
C:\Users\user>nslookup education.qld.gov.au Server: one.one.one.one Address: 220.127.116.11 DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. *** one.one.one.one can't find education.qld.gov.au: Server failed C:\Users\user>nslookup education.qld.gov.au 18.104.22.168 Server: dns.google Address: 22.214.171.124 Non-authoritative answer: Name: e38548.dsca.akamaiedge.net Addresses: 2600:1415:11::1720:5be 2600:1415:11::1720:5b0 126.96.36.199 188.8.131.52 Aliases: education.qld.gov.au education.qld.gov.au.edgekey.net
And switching to a different internet connection with 184.108.40.206 still set, suddenly the NSLOOKUP works fine. I already tried a purge-cache for the domain too.
I contacted my ISP and they told me other people have reported the same problem already, and recommended I switch to a different DNS setting.
Is this a problem on the domain hosts end or something with the Cloudflare datacenter closest to me?
