Summary
Serco NA
business enterprise government
Two netnames record a carrier, the word legacy, and the company that carrier absorbed.
What it's used for
- A government services contractor's network. 1,792 addresses across four IPv4 prefixes, with two observed BGP neighbours and no IPv6 announced.
Notable
- Two blocks are registered to
CenturyLink Communications, LLCunder the netnamesCENTURYLINK-LEGACY-SAVVIS-BLK85andCENTURYLINK-LEGACY-SAVVIS-BLK186. - The other two carry
SERCO-IN10-72andNET-209-27-15-0-1. - The contractor's name is written three different ways across the records, with and without a corporate suffix.
- One of twelve sampled addresses answered, with
serconamailgw3.serco-na.com.
Interesting
- A netname carrying both the current carrier and the acquired one, with the word for inherited space between them, is a bulk rename done properly. Somebody renaming thousands of records at once chose to keep the old name visible so that engineers looking for the previous company's space would still find it.
- That is the opposite of the usual outcome, where an acquisition leaves the old name alone and the connection between the two is left for a reader to guess.
- The published hostname marks a mail gateway and numbers it third, so at least three of them handle mail for a contractor whose correspondence is largely with government agencies.
- Two upstreams and one named host is a small, careful public footprint for an organisation whose work is mostly conducted on somebody else's networks.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 2026-10-20. 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.
