I strongly suggest you read up more about networking because it's
obvious you don't really understand it. All network traffic goes to *IP
addresses* not domains. DNS says what addresses to use for a specific
domain, but *all* connection attempts, whatever the protocol, are to a
specific numeric IP address. Yes, protocols like HTTP then accept a host
specification for further "routing" but that happens *after* the initial
connection is made.

If you want to run N jails with N different domains, all with their own
traffic to arbitrary ports, you are going to need at least N different
IP addresses.
