Summary
Prince William County Service Authority
government infrastructure
A water utility's block still carries a defunct carrier's initials.
What it's used for
- A county water and sewer authority's network. A single IPv4
/24announced from the United States, no IPv6, and a single observed BGP neighbour.
Notable
- The netname is
UU-208-250-70: two letters from a carrier brand that has not traded under that name for many years, followed by the first three octets of the block. - The block is registered to the authority itself despite that netname.
- The registrant writes the organisation's name entirely in capitals while the holder record uses title case, so the same name appears twice in two forms.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- The same two-letter carrier prefix turns up on unrelated holders elsewhere in this corpus, including a financial firm. It is a bulk label from a network that no longer exists under that name, and it outlives every organisation that carries it.
- A single upstream for a utility that runs water and wastewater systems is the exposure worth noting. Whatever this network reaches, it reaches through one relationship.
- Capitalisation differences between the holder and registrant fields look trivial and break exact matching completely. Two records for one authority, differing only in case, will not join without a normalisation step nobody remembers to add.

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.
