Summary

BYDMAN

Poland · AI-generated

education isp business

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.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 432 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
