Is this advice for using hub so that more than one computers can connect

Yes. The cable modem is the dns and default path for the Internet.

A cable modem is a layer 2 device, it is not the DNS it simply
bridges the Ethernet to the cable modem termination system (CMTS).
Some cable modems have routers built in, these may have the ability
to act as DNS proxy.
My DSL router acts as the default route AND dns server -- comcast
can't do that?!?
Comcast's DNS is in the middle of their network. The default route
is usually the CMTS (it's the next hop). When Comcast puts in
a router then the user has a similar setup to yours but I think
that's a more expensive service. Most users drop a hardware NAT/
Firewall/Router in to do this. My setup is a bit more extreme, I
need a local DNS for my devices (I can't remember every IP address
and names are easier). I think most consumer DSL is PPPoE and
needs to have that router (I'm not 100% sure of that). The cable
setup doesn't need one (but many recommend the hardware NAT/
Firewall/Router anyway). I've heard of a few cable modems that are
built in a router but I've not seen them. That would also be like
your setup.
