Summary
Government Technology Services Inc. (UNICOM Government)
enterprise legacy
The network of Government Technology Services, Inc. (GTSI), the Chantilly, Virginia IT reseller now doing business as UNICOM Government, Inc.
What it's used for
- Corporate networking for the company; reverse DNS on the space resolves to mail and other corporate hosts under
gtsi.com. - Announces thirteen
/24s from192.254.16.0/20, assigned to GTSI in the early 1990s.
Notable
- Not a government agency. Despite the name, GTSI was a commercial value-added reseller — at one point the largest VAR serving the US federal government market — founded in 1983 and listed on NASDAQ.
- UNICOM Global acquired GTSI in 2012 and renamed it UNICOM Government in 2013, but the ARIN registration still carries the original company name and the
GTSIhandle.

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.
