IIRC this should be very easy to do with dnsmasq. Just one line in the
configuration stating that www.apple.com is our IP. Comment in config
file states that we can define a domain to be served as local, so we
might have to grab the whole apple.com but a simple test should reveal
the facts.

address=/apple.com/192.168.1.1

dnsmasq can act as a DHCP server as well, so it should cover quite
well what services we need.

I believe all vendors are more or less doing the same test, so we
might need to cover quite a bit of different connectivity tests.
