CanYouSeeMe.org - Open Port Check Tool

This is a free utility for remotely verifying if a port is open or closed. It is useful to users who wish to verify port forwarding and check to see if a server is running or a firewall or ISP is blocking certain ports.

Background

Most residential ISP's block ports to combat viruses and spam. The most commonly blocked ports are port 80 and port 25.
Port 80 is the default port for http traffic. With blocked port 80 you will need to run your web server on a non-standard port.
Port 25 is the default port for sending and receiving mail. ISPs block this port to reduce the amount of spam generated by worms on infected machines within their network.

What Is My IP?

This website is dedicated to helping users across the world not only locate their IP address, but perform an IP address lookup, learn how to trace email, and learn how to change IP address. Learning your own IP address is crucial for online gaming, tech support, using remote desktop connections, detecting proxies or even running an email server. We also host a forum for our users to learn and help others with IP related questions.
What Is An IP Address?
An IP address is an exclusive number online devices use to identify and communicate with each other through computer networks. This process can best be compared to how we receive mail to our home address. An IP address would be most similar to a mailing address, while the network would be compared to the town you live in. Just like our home addresses, information cannot be sent or received by devices without a specific address.
Internet Speed Test
An internet speed test will show you the results of the fastest upload and download burst rates during your internet speed test from your location to the location of the test server you choose. TCP/IP degrades over distance so choose the server closest to you when performing the internet speed test.
IP Address Lookup
The IP Address Lookup tool also referred to as IP Lookup, Lookup IP, Lookup IP Address, IP Address Location, IP Location, and IP Locator is designed to give you an idea of where your IP Address or the IP Address you lookup is located.
