Command to display DNS server addresses

[Phaete]

What's the command to display the DNS server addresses when client IP's are assigned byt the ISP's DHCP server?

ifconfig -all doesn't quite go as far as Windows' ipconfig /all .... is there another command?

There are probably other methods but one tool is nslookup. If you know the name of your ISP domain it helps as you can use the command: nslookup in a teminal window.

Example....

nslookup
> myisp.com

displayed the following

Server: xxx.xxx.xxx.xxx
Address: xxx.xxx.xxx.xxx #53

Type exit to get out of nslookup. The number with #53 is the ISP DNS address.

I'm not sure about other distros but, in Redhat, you can check the file /etc/resolv.conf

Yep, /etc/resolv.conf is the file you're looking for. It's not RH-specific, it's used for anything using a recent-enough version of glibc (recent-enough being at least glibc 2.2, and perhaps earlier glibc versions).
