AS34309 — LINK11 Link11 GmbH

AS34309 announces 9 IPv4 prefixes covering 18,944 addresses and 2 IPv6 prefixes.

About this network

The AS handle LINK11 is held by Link11 GmbH, a European cybersecurity vendor specializing in DDoS protection and traffic management.

What it's used for

• The address space carries infrastructure for a security provider, with netnames such as DE-LINK11-20050811 and DE-LINK11-20041124 registered to Link11 GmbH.
• The AS announces 18944 IPv4 addresses across 15 prefixes and 9 IPv6 prefixes, while maintaining 158 observed neighbours; this ratio of moderate address space against a high neighbour count indicates a transit or peering-heavy role rather than a pure access network.

Notable

• Registrants for the majority of prefixes align with the announcer, listing Link11 GmbH Hostmaster and Link11 GmbH Abuse Mailbox, though one prefix (52.128.20.0/24) is registered to Dosarrest Internet Security LTD under the netname DISL4.
• The address inventory is finely subdivided into multiple /20, /21, /23, and /24 blocks, reflecting an internal corporate estate segmented by site or service rather than a single contiguous allocation.
