Summary

Xchange Telecom

United States of America · AI-generated

telecom business us

XCHANGETELECOMCORP is operated by Xchange Telecom Corp.

What it's used for

  • The address space carries corporate and legacy infrastructure, with reverse DNS entries consistently pointing to xchangetele.com across multiple blocks.
  • The AS announces 18,944 IPv4 addresses across 12 prefixes and 1 IPv6 prefix, while maintaining only 5 observed neighbours, a ratio indicative of a business or internal corporate estate rather than a transit provider.

Notable

  • Registrants are mixed, including Xchange Telecom Corp., THEJNET, Cogent Communications, LLC, and PSINet, Inc., reflecting a history of acquisitions and space transfers.
  • Xchange Telecom is an acquired company based in Brooklyn, founded in 2002, that operates as a connectivity solutions provider offering internet, voice, and mobile services.
  • The inventory includes distinct blocks such as 66.128.0.0/20 and 38.105.204.0/22, with the latter registered to Cogent, suggesting retained or leased space from previous operators.

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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
