Summary

Dominion Energy Services

United States · AI-generated

enterprise legacy

DRS-1 belongs to Dominion Energy Services, Inc., the shared-services arm of Dominion Energy, the electric and gas utility headquartered in Richmond, Virginia.

What it's used for

  • Corporate IT and utility business networking for Dominion Energy. The two announced /22s sit inside 158.106.0.0/18, a block whose ARIN record still carries the netname VANCPOWER and the registrant Dominion Virginia Power.
  • The footprint is small (about 2,048 addresses) and carries no public subscriber pools; a utility of this size runs most of its estate on private addressing behind these blocks.

Notable

  • Enterprise, not an ISP. Utilities frequently hold an ASN purely to multihome their corporate and operational networks, which is what this looks like.
  • The parent address block was registered with ARIN in 1992 and the ASN in 1997, so the low number is a genuine legacy allocation from the era when large US corporations were first getting BGP-connected.

Interesting

  • The stale VANCPOWER netname is a reminder that registry names outlive corporate rebrands: Virginia Power became Dominion Virginia Power and then Dominion Energy, but the netname never changed.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
