education k12 texas us

LUBBOCKISD-ASN is held by Lubbock Independent School District.

What it's used for

  • The space carries the district's internal network, identified by the netname LUBBOCK-ISD and registrant Lubbock Independent School District.
  • The AS announces 4096 IPv4 addresses across 1 prefix (67.158.80.0/20) with 2 observed neighbours, a ratio consistent with a single-site or small multi-site institutional network rather than a transit or access provider.
  • Traffic from this AS consists of staff, students, and administrative systems for a public K-12 school district serving 49 schools in Lubbock, Texas.

Notable

  • The RDAP registrant Lubbock Independent School District matches the AS holder and the netname LUBBOCK-ISD, confirming consistent ownership.
  • The address inventory is a single /20 block, typical for an organization that has allocated a contiguous range for its entire campus infrastructure.

Reputation

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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
