What kind of IP address is this? (WIN-F9PTTKUMI2U:29901)

While downloading a file with μTorrent, I noticed a strange peer with an address that was not an IPv4 or IPv6 address.

μTorrent showed it as WIN-F9PTTKUMI2U:29901.

What kind of address is this?

"What kind of IP address is this? (WIN-F9PTTKUMI2U:29901)"

WIN-F9PTTKUMI2U:29901 is not an IP address.

It identifies a socket connection of a particular μTorrent peer and has the format hostname:port.

• WIN-F9PTTKUMI2U is the hostname.

• 29901 is the port number.

Peers

The Peers tab is where you'll find information about all the peers you are currently connected to on the selected torrent. The following is a description of each column:

• IP displays the peer's IP address and the flag of the country they're from. If Resolve IPs is enabled, the country flag and hostname will be displayed instead.
