What it's used for

  • The address space carries corporate infrastructure for a state-owned energy utility, as indicated by the registrant Companhia de Geracao Termica de Energia Eletrica and netname 155017.
  • The AS announces a single IPv4 prefix, 177.10.112.0/22, comprising 1024 addresses, with 8 observed routing neighbours.
  • Traffic from this AS consists of internal corporate network traffic for office workers and industrial control systems supporting thermal power generation and transmission operations.

Notable

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
