Summary

Oncor Electric Delivery Company

United States of America · AI-generated

utility corporate business infrastructure

The AS handle ONCOR-1 is held by Oncor Electric Delivery Company, LLC.

What it's used for

  • The address space carries internal corporate infrastructure for a major electric utility, evidenced by the netname ONCOR-INET and registrant Oncor Electric Delivery Company, LLC.
  • The AS announces 2048 IPv4 addresses across 3 prefixes and maintains 3 observed neighbours, a ratio consistent with a segmented internal corporate estate rather than a transit or access network.

Notable

  • All registrants for the announced prefixes agree with the announcer, listing Oncor Electric Delivery Company, LLC as the network administrator.
  • The address inventory is finely subdivided into three contiguous blocks within the 199.16.160.0/22 range, reflecting site-by-site segmentation typical of large utility operations.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
