Reverse DNS Look Up


I’m trying to get the IP address of a domain name, so I can add the IP to my firewall but I can’t seem to get the dns node to work -

Is anyone using this successfully for reverse look ups ?

I’m simple trying to send the domain name (e.g via an inject node to the dns node (set to Reverse) to see if it can return the IP address via debug node ?

I’ve tried variations of the domain name, http:/,, - it all I seem to get in return is this error, and nothing reaches the debug node

That makes no sense, so you get the error. is not an address.

Either you should do a simple lookup, or rethink what you want to achieve.

Exactly this.

domain -> exec node: nslookup -> output. Or use dig +short instead.


I'm not sure what you wanted to say in your reply.

@nodecentral needs to select "lookup" instead of "reverse" in the dns node.

Thanks all, the 'lookup' option worked a treat !
