Online port scanner

IP/host tools

Checks if a TCP/IP port is opened on a remote host online.

Attempts to connect to (scan) a given host by a specific TCP/IP port number. Useful for testing BitTorrent, uTorrent connectivity, firewall/NAT configuration (port forwarding), etc. 

Opened port means that your computer is listening and accepting connections on that gateway while closed port means it won't talk to anyone attempting to connect to that port number. This port scanner lets you find which TCP/IP ports are opened and which are closed on your or other Internet machine. 

Note that port scanning takes time (1 second of timeout per each closed port) so don't submit the form twice – it won't make the process faster. 

Your IP is 38.107.179.234. Separate multiple IPs/hosts by comma, space or new line.

Max size of the input data is 10 MiB.

Wrappers are executed in sequence on shared data string. For example, to supply base64-encoded stream of GZIP-compressed data enter wrappers: base64, gzip and fill the data input with the base64 stream. 

If data is not entered information from other tabs (upload, by URL and direct) is used to replace data on this page. This lets you enter gzip as a wrapper here and upload a file using upload tab while leaving data on this page empty. 

Currently supported wrappers are: base64, bzip, cslashes, datauri, direct, ftp, ftps, gzip, hex2bin, http, https, qprintable, upload, url, urlencoding, zlib.
