Summary

City National Bank of Taylor

United States of America · AI-generated

bank business enterprise

The AS handle CNBT-AS is held by City National Bank of Taylor.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the reverse DNS record user064.cnbt.com and netnames such as CITYN-4 and SBC067064065000020923.
  • The AS announces 1280 IPv4 addresses across 5 prefixes with only 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal office workers and banking systems for a community bank operating in Taylor, Texas.

Notable

  • Registrants for four of the five prefixes are listed as "City National Bank of Taylor" or "THE CITY NATIONAL BANK OF TAYLOR", while the prefix 96.47.212.0/24 is registered to "zColo" with the netname ZCOLO-NETBLOCK-05.
  • The address inventory is finely subdivided into five /24 blocks, consistent with site-by-site segmentation for a corporate estate.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
