You mean DNS? Absolutely can self host those if you have a stable IP address. I ran djbdns for years, although it was on a xen VPS slice in a datacenter, not in my home.
The information you file with your domain registrar includes at least two IP addresses (which can be the same) and names (which must be different) for the primary name resolvers for your domain. The registrar communicates those to the right upstream layer - in the case of .com, that means a query to a.gtld-servers.net asking for an NS record for example.com will get a response with your DNS server’s name (perhaps a.ns.example.com or ns1.example.com) as well as a “glue” answer (in the same response) of an A record that defines the IP address for that name. Any recursive resolver will then ask your server for the subdomain records.
You can update records on your nameserver at any time, but you’re subject to some delays in updating those glue records and it’s not automated, so you really don’t want them to be dynamic addresses.
It gets more complicated with DNSSEC.
