- What is a glue record? 4 answers
I have a client whose website has intermittent issues, which I believe are due to DNS lookup. When this happens and they do a ping, the host cannot be resolved. Therefore, I ran:
dig @a.gtld-servers.net autoquarterly.com
;; ADDITIONAL SECTION: ns1.hostlatch.com. 172800 IN A 188.8.131.52 ns2.hostlatch.com. 172800 IN A 184.108.40.206
but these are not the correct IP addresses. If I do nslookup on the two nameservers, I get the correct IP addresses.
My question is where are these incorrect nameserver IP addresses coming from? I was under the impression these were glue records which are registered with the domain registrar. However, I noticed every domain I look up has the nameserver IP addresses in the ADDITIONAL section even though only domains which use a subdomain of their own domain name for their nameservers need glue records.
