NSlookup Query Tool

The following queries can be performed on this web-site. Where possible there are cross-links between the various queries. From these pages you are able to lookup:

• a person using a NIC handle
• What objects a person is a contact for
• who owns an IP address or address block
• who owns an IPv6 address or address block
• who owns a domain name
• DNS information for a domain name
• Check a host or domain on multiple name servers
• Who owns an Autonomous System Number
• Frequently Asked Questions about this site

I have put some more work into the searching and it will now look up a lot more domains than previously. If your results come out with no coloured boxes then it means I don't (yet) know how to parse the raw output, but I probably will soon.

Currently this set of webpages is able to understand the output of over 110 NIC (Network Information Centre) whois servers located around the world. That's over 25 different output formats. More are added each day.

NSlookup Query Tool

This form will perform various NSlookups (Name Server lookups) to find out various information about a particular host or domain name. By entering a domain name below, you can find out the domains name, web, mail and ftp servers. It tries to intelligently guess if you entered in a domain or host too.

Below the domain is the SPF (Sender Policy Framework) entries that can tell mail servers where email for the domain should be coming from.

Definitions

• Nameserver: These are the servers that the internet uses to find out more about the domain. Usually they are an ISP's computer.
• Mailserver: Where email is sent to. If there is more than one entry then the one with the lowest preference (pref= X) is tried first.
• Webserver: Pretty obvious, the domains website.
• FTPserver: FTP is file transfer protocol, this server is where files may be stored.
• Hostname: The name of the host as given by the domain.
• Real Hostname: This is hostname that you get by reverse resolving the IP address, may be different to the given hostname.
• IP Address: Unique four numbered identifier that is obtained by resolving the hostname. You can click on the address to find out who owns the address block.

Received Spam from Nigeria? Read this!!

If you recieve email from Nigerian sources proposing either a "legitimate" business deal or one where they have a large sum of money and need assistance getting it out it is extremely likely you have been emailled by fraudsters. Read more on the 419 Coalion Website about this crime and how dangerous it can be to you.

Problems? Suggestions?

I'm always looking for suggestions and new NICs to add to the system. If your favourite NIC is not working here let me know. Or if you have a problem with a particular lookup I'd like to know that too.
