Summary

ZTVI

United States of America · AI-generated

transit nsp mixed

ZTVI is the AS handle for ZTVI - Metro Communications Company.

What it's used for

  • The address space carries a mix of individual and corporate holdings, with netnames including ANDREWHOWARD-AU for Andrew John Howard, USERW-1-V4-01 for Userworld INC., and ZTVI-V4-1 for ForwardingPlane, LLC.
  • The AS announces 2560 IPv4 addresses across 8 prefixes and 11 IPv6 prefixes, while maintaining only 6 observed neighbours, a ratio that suggests a transit or network service provider role rather than a large access network.

Notable

  • Registrants do not uniformly match the announcer, listing Andrew John Howard, Userworld INC., and ForwardingPlane, LLC alongside the primary holder.
  • The inventory is fragmented, with the majority of IPv4 space registered to an individual (Andrew John Howard) under the netname ANDREWHOWARD-AU, while other blocks belong to distinct entities like Userworld and ForwardingPlane.

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 1,773 prefixes, as published 2026-10-13. 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.
