AS31572 PHOTONIUM-AS
Unclassified RIPE
Summary
Photonium NetSolutions GmbH
business germany small
The AS handle PHOTONIUM-AS is held by Photonium NetSolutions GmbH.
What it's used for
- The address space carries corporate infrastructure, evidenced by netnames
DE-PHOTONIUM-20091124andPHOTONIUM-NETregistered to the holder. - The inventory consists of 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 21 observed neighbours; this ratio of modest address space to a significant number of peers suggests a business network with multiple upstream or peering relationships rather than a large-scale access provider.
Notable
- Registrants for both announced IPv4 prefixes align with the AS holder, listing Photonium NetSolutions GmbH and associated hostmasters.
- The address inventory is compact, comprising two distinct IPv4 blocks (109.71.216.0/21 and 195.234.104.0/22) and a single IPv6 /32, indicating a focused corporate estate rather than a broad consumer base.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
