HARRIS-COUNTY-ESD11-01 is operated by Harris County ESD 11 Mobile Healthcare.

What it's used for

  • The address space carries internal network infrastructure for a mobile healthcare provider, evidenced by reverse DNS entries pointing to hcesd11.network and the netname HARRIS-COUNTY-ESD-11.
  • The AS announces 256 IPv4 addresses within a single /24 prefix (207.174.60.0/24) and maintains 3 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or large access network.

Notable

  • Harris County ESD 11 launched ESD 11 Mobile Healthcare to take over providing emergency services to residents in north Harris County, Texas.
  • The inventory consists of a single contiguous /24 block with no IPv6 prefixes, reflecting a focused, site-specific deployment.

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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
