Cisco being used as DNS server?

I was doing some research and it appears as if you can use certain Cisco routers as DNS servers?
Can someone briefly explain if this is better/worst than having a software based DNS solution (win2k DNS service etc)?

You can do the same with DHCP I saw too.  Which would be better, using your router for just routing. Or using it as a DNS server etc?
Thanks

Depends how much traffic you intend to have.  Usually, I have left DNS and DHCP to the servers....but on occasion have had to activate DHCP or DNS due to failure of a DNS or DHCP server at least for a little until repair can be done.

It works fine...never had problems...though I'm sure if you are looking at performance for a large office it might get a bit bogged down due to Internet traffic in the morning or lunch when people turn on their PCs looking for IP addresses on top of the original routing purpose.
