AS7876 DRS-1

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.
