About this network

The AS handle IMOS-AS is held by imos Gesellschaft fuer Internet-Marketing und Online-Services mbH.

What it's used for

• The address space carries residential broadband access, evidenced by reverse DNS entries such as ppp-46-17-246-254.pool23.filstalnetz.de and ppp-185-38-54-254.pool8.filstalnetz.de, which indicate PPPoE dial-up or DSL pool connections.
• The network announces 16,896 IPv4 addresses across 18 prefixes and 2 IPv6 prefixes, while maintaining 91 observed neighbours; this ratio of moderate address space against a high neighbour count suggests an access provider with significant peering relationships rather than a pure transit carrier.

Notable

• Registrants for the largest prefixes consistently identify imos NCC or imos Gesellschaft fuer Internet-Marketing und Online-Services mbH, aligning with the AS holder, though smaller blocks are registered to I-NetPartner GmbH, CSNETWORKS GmbH, and Provitex GmbH.
• The address inventory is fragmented into multiple /22 and /24 blocks, including a large /19 block, reflecting a history of incremental acquisition or consolidation of smaller ISP holdings.
