Routers just need to treat packets to 8.8.8.8 as "send this to the DNS server".
Seriously. IPv4=8.8.8.8 means "this goes to the DNS server". The DNS server helps you find all the other IP addresses you need, which is why this one is special. One DNAT rule, one SNAT rule, and you're done.

IMO IP should have had this feature from day one.
