government county colorado

ELPASO-COUNTY-GOVERNMENT-COLORADO is operated by El Paso County, Colorado.

What it's used for

  • The address space carries government infrastructure, indicated by the netname EPCCO and registrant El Paso County.
  • The AS announces 1024 IPv4 addresses within a single prefix (204.153.240.0/22) and has 1 observed neighbour, suggesting a small, self-contained internal network rather than a transit or large access provider.

Notable

  • The registrant El Paso County matches the AS handle and the announced prefix owner.
  • The address inventory consists of a single contiguous /22 block, typical for a municipal or county government entity managing its own internal IT infrastructure.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
