Editing IP over Avian Carriers (section)

== Real-life implementation ==
On 28 April 2001, IPoAC was implemented by the [[Bergen]] Linux user group, under the name CPIP (for Carrier Pigeon Internet Protocol).<ref>{{cite web |title=RFC-1149 - The highly unofficial CPIP WG |url=http://www.blug.linux.no/rfc1149 |url-status= |archive-url=https://web.archive.org/web/20140215072548/http://www.blug.linux.no/rfc1149/ |archive-date=2014-02-15 |access-date=2002-04-01 |work=BLUG}}</ref> They sent nine [[Packet (information technology)|packet]]s over a distance of approximately {{convert|5|km|mi|abbr=on|sigfig=1}}, each carried by an individual pigeon and containing one ping ([[ICMP echo request]]), and received four responses.

This real-life implementation was mentioned by the French member of parliament [[Martine Billard]] in the French [[Assemblée Nationale|National Assembly]],<ref>{{cite web|url=http://www.assemblee-nationale.fr/13/cri/2008-2009-extra/20091030.asp|title=Assemblée nationale ~ Troisième séance du mercredi 22 juillet 2009|quote=J’avais été choquée, monsieur le ministre, de vous entendre parler de pigeons voyageurs, mais, finalement, vous aviez peut-être raison. Il existe en effet une norme, la norme RFC 1149, qui date du 1er avril 1990 bien que ce n’est pas un poisson d’avril (Sourires), qui décrit comment on peut faire une transmission internet par pigeon voyageur. Neuf paquets de données ont été envoyés.|access-date=2013-02-11|archive-date=2013-03-07|archive-url=https://web.archive.org/web/20130307104853/http://www.assemblee-nationale.fr/13/cri/2008-2009-extra/20091030.asp|url-status=live}}</ref> during debates about [[HADOPI]].
