Summary

Migadu

Switzerland · AI-generated

email hosting swiss business

MIGADU is operated by Migadu-Mail Gmbh.

What it's used for

  • The address space carries outbound mail traffic, evidenced by reverse DNS entries such as out-128.trx0.migadu.com and out-64.mta0.migadu.com.
  • The AS announces 1024 IPv4 addresses across 3 prefixes with only 1 observed neighbour, indicating a dedicated endpoint for sending email rather than a transit or access network.
  • Traffic consists of SMTP sessions for multi-domain email hosting, serving subscribers who use Migadu for personal or business correspondence on custom domains.

Notable

  • All registrants align with the announcer, consistently listing Migadu-Mail Gmbh under netnames CH-MIGADU and CH-MIGADU-20220624.
  • The inventory is small and finely subdivided into three distinct blocks, reflecting an internal corporate estate segmented by function or site rather than customer base.

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: 453 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.
