Summary

3Com Net Router

United States of America · AI-generated

business corporate legacy

The AS handle 3COM-NETROUTER-ALPHA is held by 3Com Net Router.

What it's used for

  • The space carries corporate infrastructure, evidenced by the netname 3COM-NET-23-139-140 and the registrant 3Com Net Router.
  • The inventory consists of 256 IPv4 addresses and 43 IPv6 prefixes, with only 1 observed neighbour, indicating a small, isolated corporate estate rather than a transit or access network.

Notable

  • The registrant 3Com Net Router matches the AS holder name exactly.
  • The address inventory is minimal, comprising a single IPv4 /24 block and a series of IPv6 /47 and /46 prefixes under the 2602:f635::/47 range.

Reputation

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: 455 networks and 1,854 prefixes, as published 2026-11-09. 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.
