In this article, we cover how to determine where the DNS for a domain is hosted. This will be the location where changes need to be made if they are needed.
- Dig the top-level domain at the root nameserver to find the top-level domain nameserver. For example.com you would use the following command:
~ dig +short SOA com
a.gtld-servers.net. nstld.verisign-grs.com. 1597810091 1800 900 604800 86400
- Dig the domain at the nameserver returned in the previous command; the nameservers used by the domain will be located in the authority section.
For example.com you would use the following command:
~ dig NS example.com @a.gtld-servers.net.
;; AUTHORITY SECTION:
example.com. 172800 IN NS a.iana-servers.net.
example.com. 172800 IN NS b.iana-servers.net.
