Summary

mailXpert GmbH

Switzerland · AI-generated

business email swiss cloud

The AS handle RAVANA2 is held by mailXpert GmbH.

What it's used for

  • The address space carries email marketing infrastructure, evidenced by reverse DNS entries such as s01.b09.ip.mailomat.cloud and d07.b08.ip.mailxpert.cloud.
  • The network announces 256 IPv4 addresses across 1 prefix with 1 observed neighbour, indicating a small, self-contained business network rather than a transit or access provider.

Notable

  • The RDAP registrant mailXpert GmbH matches the AS holder, confirming consistent ownership of the MAILXPERT-NET netname.
  • The address inventory consists of a single /24 block, which is finely subdivided for internal use within the company's cloud services.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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 1,848 prefixes, as published 2026-10-31. 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.
