Summary

GlobalConnect

Sweden · AI-generated

transit backbone isp

948 BGP neighbours, 298 IPv4 prefixes, and reverse names with in-addr left visible inside them.

What it's used for

  • Nordic backbone and transit. 553,984 addresses in 298 IPv4 prefixes, 64 IPv6 prefixes, and 948 observed BGP neighbours.

Notable

  • The AS handle is IPO-EU, while the registry holder is GlobalConnect AB and the registrant on most blocks reads IP-ONLY Registry.
  • Netnames run from SE-GLOBALCONNECT-990914 through the 2000s to 20081119 — a decade of allocations under one name.
  • A separate family, SE-DGCSYSTEMS-20021203 and SE-DGCSYSTEMS-20040322, is registered to DGC Systems and Iver Sverige AB.
  • 137.133.128.0/17 is netname ABB, registered to ABB GTO Network Tower.
  • Two sampled addresses answer 255.191.241.83.in-addr.dgcsystems.net and 254.223.241.83.in-addr.dgcsystems.net.

Interesting

  • Those reverse names have the machinery showing. 83.241.191.255 reversed is 255.191.241.83, which belongs in front of in-addr.arpa; here the whole construction has been grafted onto a company domain instead, so the label in-addr survives in a name that is otherwise ordinary. It is the plumbing of reverse DNS appearing in its own output.
  • 948 neighbours is the number that defines this network. Almost a thousand adjacencies is not a customer base, it is a position — the AS other Nordic networks reach each other through.
  • Three company names across the netnames, plus ABB's own /17 carried inside, is a backbone assembled by acquisition. IP-Only survives in the AS handle, DGC in the reverse zone, and GlobalConnect on the deeds.

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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
