Summary

FLAG Telecom UK

United Kingdom · AI-generated

transit telecom isp infrastructure

A submarine cable carrier with three hundred and eighty neighbours, carrying blocks from another region's registry.

What it's used for

  • A long distance carrier built around undersea cable. Twenty-two IPv4 prefixes and one IPv6 /32 announced from the United Kingdom, thirty-three thousand addresses, across three hundred and eighty observed BGP neighbours.

Notable

  • Five blocks use the carrier's own netname pattern of country code, company and allocation date, with an abuse role naming the group that acquired it.
  • Six more are customer blocks registered in a different region's registry, each with a two letter country suffix and an incident response team object, a convention that registry uses and the other does not.
  • One block is registered to the carrier's arm in a third country.
  • Two answering addresses combine a word for delivery with their octets under a domain about network management; a third puts the address fully reversed under a domain about computing analysis.
  • Eighteen addresses were queried for reverse DNS and three returned a name.

Interesting

  • Three hundred and eighty neighbours is the number that matters. That is a carrier whose business is carrying other networks' traffic between continents, and it dwarfs its own address holdings.
  • Mixing two registries' conventions inside one routing table is what selling capacity across regions looks like in the data.
  • The generic domains on the answering addresses say very little about who is behind them, which is itself a choice worth noticing.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
