AS200036 CITYNET
Unclassified RIPE Cable/DSL/ISP
Summary
CityNet
isp residential cable dsl
CITYNET is operated by CityNet, a small Italian cable and DSL provider.
What it's used for
- The space carries residential access traffic, as indicated by the PeeringDB classification of "Cable/DSL/ISP" and the netname
CityNet. - The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with 8 observed neighbours; this ratio of limited address space against a moderate number of peers suggests a local access network rather than a transit provider.
- Traffic from this AS consists of subscriber eyeballs connecting via cable or DSL infrastructure in Italy.
Notable
- The RDAP registrant
Niccolo Pietrobonmatches the registry holder, confirming consistent ownership of the address space. - The inventory consists of a single /24 IPv4 block and a /32 IPv6 prefix, representing a compact, self-contained address estate typical of a small regional ISP.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
