(Sorry, had to replace lots of dots with ‘-DOT-’ as this board doesn’t allow posting links)
I have a mydomain-DOT-com that uses Cloudflare for DNS but wanted to delegate the DNS of a subdomain mysubdomain-DOT-mydomain-DOT-com to a different one (shared hosting server on Namecheap, which already has that domain/subdomain set up in cPanel), so I added the NS records dns1-DOT-namecheaphosting-DOT-com and dns2-DOT-namecheaphosting-DOT-com for the subdomain in Cloudflare DNS.
However even after a day has passed the subdomain mysubdomain-DOT-mydomain-DOT-com doesn’t resolve (on a related note, the same setup for anothersubdomain-DOT-anotherdomain-DOT-com started working immediately yesterday, so for some reason it only doesn’t work for subdomains in mydomain-DOT-com).
Below are the last few lines of “dig +trace mysubdomain-DOT-mydomain-DOT-com @188.8.131.52”:
mysubdomain-DOT-mydomain-DOT-com. 300 IN NS dns1-DOT-namecheaphosting-DOT-com. mysubdomain-DOT-mydomain-DOT-com. 300 IN NS dns2-DOT-namecheaphosting-DOT-com. ;; Received 124 bytes from 184.108.40.206#53(rudy-DOT-ns-DOT-cloudflare-DOT-com) in 421 ms mydomain-DOT-com. 3601 IN SOA dns1-DOT-registrar-servers-DOT-com. hostmaster-DOT-registrar-servers-DOT-com. 1580327645 43200 3600 604800 3601 ;; Received 139 bytes from 220.127.116.11#53(dns1-DOT-namecheaphosting-DOT-com) in 423 ms
And below are the last few lines of “dig +trace anothersubdomain-DOT-anotherdomain-DOT-com @18.104.22.168” (the one that works):
anothersubdomain-DOT-anotherdomain-DOT-com. 300 IN NS dns1-DOT-namecheaphosting-DOT-com. anothersubdomain-DOT-anotherdomain-DOT-com. 300 IN NS dns2-DOT-namecheaphosting-DOT-com. ;; Received 109 bytes from 22.214.171.124#53(dana-DOT-ns-DOT-cloudflare-DOT-com) in 420 ms anothersubdomain-DOT-anotherdomain-DOT-com. 1200 IN A SHARED.HOSTING.SERVER.IP anotherdomain-DOT-com. 1800000 IN NS dns1-DOT-namecheaphosting-DOT-com. anotherdomain-DOT-com. 1800000 IN NS dns2-DOT-namecheaphosting-DOT-com. ;; Received 125 bytes from 126.96.36.199#53(dns2-DOT-namecheaphosting-DOT-com) in 424 ms
What’s wrong with mydomain-DOT-com?
