NSLookup is an internet utility to get domain's DNS information. It will help you to find the target IP address of a domain or see what name servers are set on a specific domain.

NSLookup for iPhone and iPad allows you to see the public DNS records of domains or sub domains. Then you may also query the NS and CNAME records. It's also possible to force it to get an authoritative response from main DNS server of the domain.

Used to work well. Now it doesn’t

It used to work well, but now it always queries internet dns servers (usually google dns) and completely ignores any dns server that I specify in settings.

I need an app to verify dns on a local, private network. This app is completely useless now that it ignores and refuses to contact my local LAN DNS servers.

Even internet DNS responses often fail to display proper A record information

Fantastic when you're diagnosing an internal DNS server and don't have a workstation in front of you.


I paid for PRO version: it’s a PRO CRASH FIASCO!!!

The free version was Ok, but after I upgraded to PRO version, it crashes within a second after starting the app. I only get a glimpse of the opening page and then it crashes.
Don’t waste your money.
