Summary

B2X Online

United States of America · AI-generated

wisp residential access business

The AS handle B2X-ONLINE-WISP-ASN is held by B2X Online Inc.

What it's used for

  • The address space carries residential and small business customer traffic, evidenced by netnames like B2XONLINE-WISP-SWVA-NETBLK-01 and reverse DNS entries such as cust254.b2xonline.net and wisp.208.69.226.254.b2xonline.net.
  • The network announces 2560 IPv4 addresses across 4 prefixes and maintains 3 observed neighbours, a ratio that indicates an access or eyeball network rather than a transit provider.

Notable

  • All registrants for the announced prefixes are listed as B2X Online Inc, consistent with the AS holder.
  • The address inventory consists of two /22 blocks and two /24 blocks, all located in the United States, with no IPv6 prefixes in the 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.
