FEXCO is operated by Fexco Unlimited Company.

What it's used for

  • The space carries corporate infrastructure, evidenced by the netname AS-FEXCO-NET and registrants including Airspeed Support Team and Fexco Unlimited Company.
  • The AS announces 512 IPv4 addresses within a single prefix (91.217.88.0/23) and maintains 2 observed neighbours, indicating a small-scale internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of business endpoints for Fexco, an Irish provider of merchant, business, and consumer financial services.

Notable

  • Registrants align with the announcer, listing Airspeed Support Team, Fexco Unlimited Company, and Abuse-C Role.
  • The address inventory is compact, consisting of a single /23 block with no announced IPv6 prefixes.

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 1,782 prefixes, as published 2026-10-16. 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.
