Summary

Lion Re:Sources UK Limited

United Kingdom · AI-generated

business media corporate

The AS handle RE-SOURCES-AS is held by Lion Re:Sources UK Limited.

What it's used for

  • The address space carries the netname PUBLICIS, indicating usage by the Publicis Groupe media and communications conglomerate.
  • The AS announces a single IPv4 prefix of 1024 addresses (193.201.132.0/22) with one observed neighbour, a ratio consistent with a small internal corporate estate rather than a transit or access network.

Notable

  • The registrant LION RE: SOURCES UK LIMITED aligns with the AS holder, and the netname PUBLICIS reflects the corporate ownership structure of the media group.
  • The address inventory consists of a single contiguous /22 block, representing a finely subdivided internal corporate estate.

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 1,783 prefixes, as published 2026-10-17. 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.
