Since when does "ifconfig" show you the DNS servers' addresses?hcuar said:
Network Preferences doesn't show them either if you pick them up via DHCP. If you set them manually, the OP wouldn't be asking the question, I wouldn't think.
Anyway, in Terminal type "cat /etc/resolv.conf"; the IP addresses of your DNS servers should be listed there.

I was wondering about ifconfig's ability to give you this kind of info too.... but even with the resolv.conf file, I get the router's address as the nameserver, and not the real DNS.
Airport Admin Utility does provide it, in the internet tab. I bet if you're using another router, you can find it in the config pages you get when you point a browser at the router's IP.
What about using nslookup and then using the "server" query?
Or contacting the ISP's technical support?

I didn't suggest looking at the router config, since I figured if the OP knew enough to get into the router, he wouldn't be asking the question.
DNS
Thanks guys for the responses. Yes, I also have a Linksys Router and yes I can into the interface and assign different local static ip's to my different mac's. example: PB: 192.168.1.100 Mini: 192.168.1.101 G4: 192.168.1.102. Unless I set the network configuration in the wireless card to DHCP I do not connect. I realize I need to add the DNS address to the if I am going to configure it manually. The ISP tech support would not disclose this info (comcast) So all I need to do is get that DNS address while I am connected while in DHCP. Hope you guys got all that lol.

The Comcast tech wouldn't give you their DNS server? Unbelievable. Call back. Tell them there are many broadband offerings out there, you're willing to seek other companies if they can't give you something as simple as a DNS server's IP address.
