Summary

San Jacinto College District

United States of America · AI-generated

education business network

SJCNET-ASN is operated by San Jacinto College District.

What it's used for

  • The address space carries institutional network infrastructure, evidenced by the netname SJCNET and the reverse DNS record ra2.sjcd.edu.
  • The AS announces 4096 IPv4 addresses across 7 prefixes with only 1 observed neighbour, indicating a self-contained internal network rather than a transit or large-scale access provider.

Notable

  • All registrants for the announced prefixes are consistent with the announcer, identified as San Jacinto College District.
  • The address inventory is finely subdivided into multiple /22, /23, and /24 blocks, reflecting site-by-site segmentation typical of a multi-campus educational institution.

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 1,854 prefixes, as published 2026-11-06. 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.
