How to Use

  • Domain: The domain to look up.
  • Query type: The type of record requested. Leaving it as “ANY” will usually collect the most information. With some servers, you need to ask for a specific type of record to get it.

After you’re done, click “Go” to run the NsLookup tool.

What it does

The tool is equivalent to the nslookup command on Unix and Linux systems.

It queries the specified DNS server and retrieves the records for the domain. They provide the domain’s IP addresses, as well as other information. The following record types are especially useful.

A: The IPv4 address for the domain.

AAAA: The IPv6 address.

CNAME (canonical name): An alias of one domain name to another. This lets a server use more than one domain name.

MX (mail exchange record): A list of message transfer agents for the domain. A message transfer agent handles email for the domain.

NS: An authoritative name server for the domain. There can be more than one NS record per domain. All other servers use a copy of information from the authoritative servers.

TXT: A record containing information for use outside the DNS. The content takes the form “name=value”. Authentication schemes such as SPF and DKIM use TXT records.
