Summary
NFON AG
enterprise voip legacy
NFON-AS belongs to NFON AG, a Munich-headquartered, publicly listed provider of cloud telephony — hosted PBX and business voice (its main product line is Cloudya) sold across Germany, Austria and much of Europe.
What it's used for
NFON's own voice platform. The AS announces roughly 2,300 IPv4 addresses in two prefixes (109.68.96.0/21 and a /24) plus one IPv6 prefix, and the sampled reverse DNS is all first-party nfon.net infrastructure: mail (smtp01.nfon.net) and platform hosts on dhcp-a-NNN.nfon.net. There is no residential naming and no third-party space. Customer handsets and SIP endpoints sit on their own access ISPs; what lives here is the service side.
Notable
- 128 observed BGP neighbours against only ~2,300 addresses. That ratio is the interesting part of this AS. It is the shape of a voice platform, which peers widely so that SIP and RTP reach customers and carriers over short, low-jitter paths, rather than of a network that needs address space.
- The
dhcp-label in the reverse DNS names an internal addressing mechanism inside NFON's platform. It is not evidence of subscriber pools. This is the same trap as PPPoE/VPN labels elsewhere. - Classified
business: an enterprise SaaS operator running its own service network, not an ISP, a host or a transit carrier.

Reputation
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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
