Summary

Southwest Power Pool

United States of America · AI-generated

utility business grid infrastructure

SPPINTERNET01 is operated by Southwest Power Pool.

What it's used for

  • The address space carries internal utility infrastructure, evidenced by the reverse DNS entry threattest.spp.org and the netname NETBLK-SPPNET.
  • The AS announces 1024 IPv4 addresses across 2 prefixes with 3 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.

Notable

  • Registrants align with the announcer for the primary block, with Southwest Power Pool listed for 192.200.62.0/23, while the secondary block 198.22.156.0/23 is registered to Various Registries (Maintained by ARIN).
  • The inventory consists of two /23 blocks, one explicitly named for the SPP network and the other a generic ARIN-maintained block, reflecting a modest internal estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-02, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
