Where 179 fits
Why 179 is special
BGP is how independent networks tell each other which addresses they can reach. It runs on trust rather than proof, so a single mis-announced route has repeatedly taken large services offline worldwide — the 2021 Facebook outage and several national-scale disruptions were BGP events, not server failures.

BGP carries the routing between independent networks, and the internet it routes for switched to TCP/IP in 1983. Routing between autonomous networks is what made a network of networks possible.

Border Gateway Protocol sessions run over TCP port 179. Because peers are configured explicitly rather than discovered, the port is normally reachable only from known addresses.
DocumentedTechnology & computingGeography: International — IETFPeriod: 1989–BGP has no way to verify that a network genuinely owns the addresses it advertises, so a mistyped announcement propagates as readily as a correct one. Outages at Facebook in 2021 and national-scale disruptions elsewhere were BGP events, and the proposed fixes have been standardised for years without being universally adopted.
