Exactly... and it is possible to have a 'URL' as your proxy.  It can contain
hints and be dynamic over time making it "easy" to update the proxy environment.
and you have a single instruction for all your 10000 users.   While
some stuff can
be done with DHCP, the URL trick is powerful and sets a stage such
that the squid
admin folk do not need  to touch a complex DHCP setup.
