I had assumed that the OP still had internet access from their other
machines.

I always think it odd that a router that issues hostnames and IP
addresses to hosts can't spit the same information out when given
a DNS query. But I've assumed that setting it up to do so would
involve no work; the work is in typing the information into the
DHCP pages.

So if you have a DNS-serving router, it would seem defeatest to
then have to maintain /etc/hosts files, and it just hides the
problem which, thankfully, has now been found.
