About this network

TITAN-NETWORKS is operated by Titan Networks Internet & Telecommunications Service Providing GmbH.

What it's used for

• The address space carries residential and business internet services, evidenced by the reverse DNS record decix.gwxs.net.fra8.titan-networks.de which indicates a gateway for the Frankfurt region.
• The AS announces 4096 IPv4 addresses across 1 prefix and 1 IPv6 prefix, while maintaining 95 observed neighbours. This ratio of a single /20 block against a high neighbour count suggests a regional access provider that aggregates traffic from multiple upstreams or peers rather than a large-scale transit carrier.

Notable

• The registrant for the announced prefix 217.173.128.0/20 is Titan Networks Internet & Telecommunications Service Providing GmbH, which matches the registry holder exactly.
• The address inventory consists of a single contiguous IPv4 block and a single IPv6 prefix, indicating a consolidated internal estate rather than fragmented leased space.
