Agreed, but my point is that if I spin up a new container with something in it, I want to be able to have DNS registration occur automatically so that I’m not having to go update DNS entries somewhere.

A simple solution would be `dnsmasq` which provides DNS and DHCP, but it cannot be used on a public network. More complex setup would be ISC DHCP server that maintains a dynamic subdomain in BIND.

PowerDNS lets you do that (if you run it against a SQL database), or CoreDNS/etcd for simple stuff.
