Summary

CheetahMail

United States of America · AI-generated

email marketing business legacy

ASN-CHEETA-MAIL is operated by CheetahMail.

What it's used for

  • The address space carries email infrastructure, evidenced by reverse DNS entries such as p1-002254.email.americanexpress.com and ny7p01lppmta259.deliverability.chtah.net, alongside netnames like CHEETAH-PUBLIC and LVLT-CHEET-1-8-7-42.
  • The AS announces 14,848 IPv4 addresses across 40 prefixes with 5 observed neighbours, a ratio consistent with a dedicated business network rather than a transit provider.
  • Traffic from this AS consists of email marketing campaigns and deliverability services, reflecting CheetahMail's role as a B2B email platform.

Notable

  • Registrants for the majority of prefixes are listed as CHEETAHMAIL, while two larger blocks (38.64.68.0/22 and 38.107.102.0/23) are registered to Cogent Communications, LLC with the netname COGENT-A.
  • CheetahMail, formerly part of Experian's marketing suite and later rebranded under Vector Capital as Cheetah Digital, ceased operations in December 2025 after 27 years.
  • The inventory includes legacy blocks with netnames referencing QWEST-EWR and LVLT, indicating historical acquisitions or migrations from Level 3 and Qwest.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
