AS31572 announces 2 IPv4 prefixes covering 3,072 addresses and 1 IPv6 prefixes.

About this network

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-20091124 and PHOTONIUM-NET registered 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.
