United States of America · AI-generated

business us ipv4 ipv6

NYCT is the AS handle for New York Connect.

What it's used for

  • The address space is registered under netnames NYCT-1BLK and NYCT-3BLK, both attributed to New York Connect.
  • The AS announces 12,288 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining only 3 observed neighbours. This high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants for both announced IPv4 prefixes match the AS holder, New York Connect.
  • The inventory consists of two distinct IPv4 blocks: 216.139.128.0/19 and 72.4.96.0/20, alongside a single /32 IPv6 prefix.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
