Summary

XtcN

United States of America · AI-generated

business vpn small

The AS handle LAMBNET is held by XtcN.

What it's used for

  • The address space carries endpoints for XtcN, evidenced by the netname XTCN and reverse DNS entries such as xn--cjy4m.xtcn.com and reserved.xtcn.com.
  • The network announces 256 IPv4 addresses within a single prefix, 192.101.186.0/24, and maintains 2 observed neighbours.
  • As a small-scale operator with a single /24 block and minimal peering, the traffic consists of internal corporate or service endpoints rather than broad residential or transit flows.

Notable

  • The RDAP registrant XtcN and netname XTCN align with the AS holder identity.
  • The address inventory is compact, consisting of one contiguous /24 block with no announced IPv6 prefixes.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-04, 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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
