Well, I can explain the advantage of usign a nameserver, but how it
relates to Squid, I don't know as I havn't messed with Squid. Anyway,
heres the advantage as I see it.

Without a nameserver, in order for each workstation to correctly resolv
another workstations IP-Address, FQDN & Hostname you would have to add the
IP-Address, FQDN & Hostname of every workstation on your LAN to the
/etc/hosts file of every other workstation on the LAN.

With a nameserver, you simply point the workstation to your nameserver,
the workstation, when needing to resolv another workstations IP-Address,
FQDN & Hostname would then simply query your nameserver, which takes care
of resolving, and relays it back to the initiating workstation.
Now, let's say you add another computer some time down the road.

In the first scenario, you would have to add the IP-Address, FQDN &
Hostname of all other workstations to this new workstations /etc/hosts
file in order for it to correctly resolv.

In the second scenario, you would only have to add the new workstation
to the nameservers zone files so that every other workstation can resolv
it.
