Summary
Nebraska Public Power District
enterprise legacy
Nebraska Public Power District (NPPDNET), the publicly owned electric utility that generates and transmits power across most of Nebraska.
What it's used for
- Corporate and operational networking for the utility — offices, generating stations, and transmission facilities.
- A single small block of 256 IPv4 addresses, the footprint of an organisation networking itself rather than serving customers.
Notable
- This is a utility corporate network: no subscribers sit behind it, so traffic from this range is a power company's own staff and systems.
- NPPD is a political subdivision of the State of Nebraska rather than an investor-owned company. Nebraska is unusual in the US for being served entirely by public power.
Interesting
- Utilities were early ASN holders because they already ran wide-area communications for grid operation, and hooking that to the internet in the mid-1990s was a short step.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
