 +# Tunnel
 +
 +
 +An IP tunnel is an [IP](/​glossary/​i/​ip) network channel between two networks. It is used to transfer data using a different [protocol](/​glossary/​p/​protocol) by wrapping its [packets](/​glossary/​p/​packet) in packets of a different type.
 +
 +In IP tunnelling, every IP packet, including addressing information of its source and destination IP networks, is encapsulated within another packet format native to the transit network.
