How do I find out the IP of provided DNS servers?

I need it to delegate those in nic.ar

Moved a site to Godaddy hosting, they gave me the dns server (primary and secondary) but not those IP. And nic.ar ask me those.
Asked support and they don't give me those still.
Is there any way to find out what they are?

Is there a tool out there to do such a thing?
ns5.bla.bla is #*$!.#*$!.#*$!.#*$!

Did you try a whois on the name servers?

Nope. I didn't find one and dunno how to. DNS site tools are overwhelming...

An aside, it's odd that G.D. won't give you the IP addresses, they're usually very cooperative. This raises a suspicion that the IP addresses for those name servers may be dynamic (not likely, but still . . . )

Any domain name registrar, including godaddy.com, will have a whois link (well, all the ones I've seen . . . ) Follow the link, enter the name server domain. It should list the IP address as part of the whois info.

Another way, in Windows:

Start->Run

Type cmd or command in the run text box, press enter (or OK button)

A number of things here will reveal an ip. type ping [servername]

ping ns1.[domainname].com

It will return 4 pings, "pinging [IP address] with 32 bytes of data"

A more complex one is tracert (trace route)

tracert ns1.[domainname].com

which traces the route from your computer to the host, but it also says "tracing route to domainname [IP address]"

If you have linux, you can just do whois from the command line

whois domainname.com
