[Ubuntu-SG] DNS on Ubuntu question

[Mark Philip]

Hi all,
I'm using Ubuntu 10.04 on a netbook.
I'm connected to Starhub at home via wifi.
When I check on my connection, it reports that my primary DNS is my
wireless router's IP address, whilst my secondary DNS is the Starhub
IP.

Is this correct? I did not enable any DNS services on the router, as
it is set to obtain the DNS directly from Starhub. As a result, when I
surf the Internet, it takes a while to look up webpages as it
traverses the primary DNS first.

Is there a way to remove the primary DNS lookup from Ubuntu and
replace it with Starhub's DNS server instead?

Many thanks,
Mark.
