isp business regional nsp

The AS handle ISPNET-1 is held by ISPnet, Inc.

What it's used for

  • The address space carries business and enterprise connectivity, with netnames including NTTA-199-224, NTTA-165-254, NTTA-204-141, and PROGPLUSNET.
  • The AS announces 2560 IPv4 addresses across 8 prefixes and maintains 3 observed neighbours, a ratio consistent with a regional network service provider rather than a large transit backbone.

Notable

  • Registrants for the majority of prefixes are listed as NTT America, Inc.; VIPAR, while the AS holder is ISPnet, Inc., indicating the address space was likely acquired from or leased from NTT America.
  • One prefix, 199.4.220.0/24, is registered to Programming Plus under the netname PROGPLUSNET, which does not align with the primary NTT America registrants.
  • The inventory consists of eight distinct IPv4 prefixes with no IPv6 prefixes in the announced inventory.

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 1,784 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.
