United States of America · AI-generated

education k12 texas public

PASADENA-ISD-AS1 is operated by Pasadena Independent School District.

What it's used for

  • The address space carries the district's internal network, identified by the netname PISD and registrant Pasadena Independent School District.
  • The AS announces 256 IPv4 addresses across 1 prefix (192.55.241.0/24) and observes 2 routing neighbours, a ratio consistent with a single-site or small multi-site institutional network rather than a transit or large access provider.
  • Traffic from this AS represents staff, students, and administrative systems for a public K-12 school district serving southeast Harris County, Texas.

Notable

  • The RDAP registrant Pasadena Independent School District matches the AS handle and registry holder exactly.
  • The address inventory consists of a single contiguous /24 block, typical for a public institution managing its own IP space for campus connectivity.

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
