Whois

There are five common questions about domain names and IPs you may have:
  1. Who owns this IP?
  2. I know the domain name. What IP does it map so I can put an entry in my hosts. file.
  3. Who owns this domain name?
  4. Where on the planet is this IP broadcasting from?
  5. What is my face IP?

1. Who Owns This IP?

For the first question, who owns or is currently using this IP, see IP lookup services

2. Finding the IP From a Domain Name

For the second question, finding the IP given the domain name, you need an DNS lookup service:

3. Finding out who owns a Domain

For the third question (who owns this domain) use one of these whois services:

You might think it sufficient for to check if a domain name is taken to simply point your browser to www.xxxxx.com and see if you get a 404 not found error. However, the name may be taken, with no webserver set up, so the name would appear to be free when it was actually taken.

4. Finding out Where a Domain/IP is Located

For third question (where is the domain located) use one of these Ip locator services:

5. Finding our Your Face IP

Ways of Finding Your Face IP
Logo Link Notes
moose Your face IP:[38.107.191.109] Your face IP is displayed at the bottom of every page of this website. I do this with SSI.
IPChicken logo IPchicken.com tells your face ip, and which ports you have open. They also tell you your face name, e.g. your URL on the web, possibly temporarily assigned for your connection. It might look something like this S010609991195576dda.gv.shawcable.net or d207-81-138-97.bchsia.telus.net That is not my real one. I don’t want to encourage hackers.
Dyndns logo checkip.dyndns.org:8245/ Offers many other services as well.
WhatIsMyIPAddress logo whatismyipaddress.com has many annoying ads you must close to discover the answer.
In a Servlet you can use javax.servlet. ServletRequest. getRemotePort().
The face ip is different from the IP of your computer on the LAN. An IP of a computer on a LAN is typically something like 192.168.2.7. The router has two ips, one it talks to the computers on the lan often 192.168.2.1 and one it uses to talk to the outside world, dynamically assigned by the ISP using DHCP.
