Summary
zGato
individual research open-source
The AS handle ZGATO is held by Marc Gomez.
What it's used for
- The space carries a single IPv4 prefix
150.251.131.0/24with netnameMGOMEZ-150-251-131-0and ten IPv6 prefixes under2001:3786::/32. - With 256 IPv4 addresses and 96 IPv6 prefixes announced against 37 observed neighbours, the ratio indicates a small-scale access or research network rather than a transit provider.
- Traffic from this AS consists of individual endpoints associated with Marc Gomez, a computer systems and networks student in Barcelona, Spain, who contributes to open-source projects.
Notable
- The RDAP registrant for the IPv4 block is listed as
Abuse-C Rolewith netnameMGOMEZ-150-251-131-0, aligning with the registry holder Marc Gomez. - The address inventory is minimal, consisting of one /24 IPv4 block and ten /48 or larger IPv6 prefixes, all announced from Spain.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
37 upstream, 0 downstream and 38 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-30, 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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
