NSLOOKUP: look up and find IP addresses in the DNS

Query a DNS domain nameserver to lookup and find IP address information of computers in the internet. Convert a host or domain name into an IP address.

This is the right place for you to check how your web hosting company or domain name registrar has set up the DNS stuff for your domain, how your dynamic DNS is going, or to search IP addresses or research any kind of e-mail abuse (UBE/UCE spam) or other internet abuse.

NSLOOKUP is a service to look up information in the DNS (Domain Name System [RFC1034, RFC1035, RFC1033]). The NSLOOKUP utility is a unix tool. If you want to learn more, here is the nslookup manual (man page).
Basically, DNS maps domain names to IP addresses.
Although this web online service can query a specific DNS server, in most cases it may be sufficient and convenient just to use the KLOTH.NET default nameserver "localhost"/127.0.0.1.
To resolve an IP address by reverse lookup (get a computer's name if you only have its IP address), try to perform a PTR query instead of ANY. This reverse lookup will only work if the IP address owner has inserted a PTR record in the DNS. The PTR information is informal only and it may mostly be true, but sometimes not. If you don't get a PTR information about a specific computer from a NSLOOKUP query, you may want to try our whois service to find out the owner of this IP address.
Like the PTR, other records are also not mandatory: LOC, RP, TXT. They are not strictly required in the DNS and their content may be true or not.
You can't trust on the LOC to locate a host, because most hosts don't have this record defined.

If you prefer dig over nslookup, you may try our dig service.
