Yes. Your question is really,
"Can name resolution to the same registered name be made with rotating IP addresses obtained through DHCP?" The answer is still yes. Dynamic host name services like DynDNS are required to keep the mapping synchronized.
The alternative is to lease static IP's from an ISP. Static IP addresses frequently come with a higher charge & require business-level accounts. IP addresses obtained through DHCP do not require business-level accounts.

I think your confusion stems from mixing IP address issues
(level 3 on the OSI network model...) with DNS name resolution which is done at a higher level in the OSI model.
pf(4) is involved with both given its need to deal with IP addresses & ports specific to DNS traffic
(ports 53 on both UDP & TCP...).
