The AS handle TCS-ASN-216-230-22-WHTSKY is held by Tuscaloosa City Schools.

What it's used for

  • The space carries the network infrastructure for the Tuscaloosa City Schools district, as indicated by the netname TCS-334 and the registrant identity.
  • The AS announces 512 IPv4 addresses within a single /23 prefix (216.230.22.0/23) and maintains 1 observed neighbour, a ratio consistent with a small, self-contained institutional network rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant Tuscaloosa City Schools matches the registry holder, confirming the ownership of the address space.
  • The address inventory consists of a single contiguous /23 block, representing a modest footprint typical of a local school district's internal network requirements.

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 1,782 prefixes, as published 2026-10-16. 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.
