The IP over Avian Carriers (IPoAC) is a humorous internet protocol that is described in RFC 1149, a document within the computer network community. It was published on April 1, 1990, as an April Fools' Day joke. The protocol suggests using homing pigeons to carry internet protocol (IP) traffic. Interestingly, it was actually implemented and tested in 2001 by the Bergen Linux user group. They sent nine packets of information over a distance of approximately 5 km (3.1 miles) using pigeons, and although the packet loss was high due to one of the pigeons going missing, it demonstrated that even the most unconventional methods could be used to transmit data!
