Comment 92 for bug 32906

Charles,

Your computer is using DHCP to acquire an IP address from the router.
As part of this transaction, the DHCP server typically also provides
DNS server addresses so that your computer knows where to ask for
translations from host name to ip addresses. Since you're connected
to a Telstra network, it's not surprising that your router is
configured to use their DNS servers. In fact, your router may be
using the DHCP to acquire its IP address and DNS information from
Telstra.

The 2-3 second pauses sound like an application (or set of them) is
blocking while waiting to perform a DNS lookups. Even on a single
host, the desktop uses many networking protocols for interprocess
communication. If the lookup for 'localhost' fails, these messages
can get stuck.

Thanks,
brian
