Summary
GGA Maur
cable dsl isp residential
The AS handle GGAMAUR is operated by GGA Maur Genossenschaft.
What it's used for
- The address space carries residential customer traffic, evidenced by reverse DNS entries such as
c-62-32-8-0.customer.ggaweb.chandstatic-c-213-160-47-255.customer.ggaweb.ch. - The network announces 61696 IPv4 addresses across 19 prefixes and 2 IPv6 prefixes, while maintaining 220 observed neighbours, a ratio consistent with an access provider connecting to multiple upstreams and peers.
Notable
- All registrants for the sampled prefixes are listed as "GGA Maur Admin; Genossenschaft GGA Maur", which aligns perfectly with the AS holder name.
- The address inventory consists of a mix of large /19 blocks and smaller /22 allocations, all registered under the
CH-GGAMAURnetname series, indicating a unified corporate estate.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
