Residential RIPE
Summary
Monzoon Networks AG
residential mobile isp switzerland
MONZOON-AS is operated by Monzoon Networks AG.
What it's used for
- The address space carries residential and mobile access traffic, evidenced by reverse DNS entries such as
mobileaccess.monzoon.net,dynamic.monzoon.net, andstatic.monzoon.net. - With 13,312 IPv4 addresses announced across 5 prefixes and 542 observed neighbours, the high neighbour count relative to the address inventory indicates a transit or peering-heavy role, consistent with a regional ISP providing both access and upstream connectivity.
Notable
- All registrants for the announced prefixes are Monzoon Networks AG, matching the AS holder and confirming direct ownership of the address space.
- The inventory consists of five distinct IPv4 blocks ranging from /20 to /22, alongside a single /32 IPv6 prefix, reflecting a mixed but consolidated Swiss access network.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
