Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I'm trying to nslookup all records of my internet provider, but it's returning "Result too large". I'm using the Windows nslookup.exe.

example:

nslookup.exe
>server ns1.brtel.com.br
>set type=ANY
>ls -d brtel.com.br > brtel.txt
ls: connect: Result too large
*** Can't list domain brtel.com.br: Unspecified error

Does anyone know how to solve this?

@Chopper3, that's the first (and necessary) step toward downloading the Internet. –  Philip Oct 15 '12 at 19:07
    
In fact i'm trying to find all hosts that are connected(via cable modem) to my Internet Provider. –  user141179 Oct 15 '12 at 19:18

Providers generally won't let you do that. –  gparent Oct 15 '12 at 20:01

@user141179, and why do you think you deserve to have all that information? What kind of abuse to you plan on performing once you get it? –  Zoredache Oct 15 '12 at 20:22

Most DNS Servers restrict the answer to a 512 Byte UDP Packet. If the response is bigger than that then you get the error you're looking at. The solution is either to request less domains at a time or get your provider to up the limit on DNS requests, which is a bit unlikely.
