About this network

A university-run metropolitan network in Bydgoszcz, carrying a village's fibre build under its own netname.

What it's used for

• Academic and regional connectivity in Poland. 30,976 addresses in 20 IPv4 prefixes, two IPv6 prefixes, and 20 observed BGP neighbours.

Notable

• The registrant on nearly every block is Politechnika Bydgoska im. Jana i Jedrzeja Sniadeckich, the Bydgoszcz university of technology.
• Netnames run PL-BYDMAN-990511, PL-BYDMAN-20060619, PL-BYDMAN-20081212, PL-BYDMAN-20110208 and PL-BYDMAN-20110216.
• Four blocks are named for what they serve instead: OSIELSKO-NET-3, OSIELSKO-NET-GPON, PBSCOM-BYD and TELSTEN-BYD.
• The IPv6 announcements are 2001:90c::/31 and 2001:90e::/32.
• Eighteen sampled addresses were queried and none returned a name.

Interesting

• MAN in the name is metropolitan area network, and Polish academic networking is built out of them: a university in each city runs the regional infrastructure and everyone else connects through it. The addresses belong to the polytechnic, but the customers plainly do not.
• OSIELSKO-NET-GPON names a fibre access technology and a rural gmina outside the city. A village getting fibre through the local university is a funding model as much as a network design, and here it is written into the address registry.
• A /31 of IPv6 is twice the standard allocation and an odd size to hold. Academic networks were early to IPv6 and were given room accordingly, at a time when nobody was counting.
