About this network

STADTKOELN1 is operated by Stadt Köln, the municipal government of Cologne.

What it's used for

• The address space carries municipal network infrastructure, identified by the netname CAN-MAN and registrant Stadt Koeln.
• The AS announces 16,384 IPv4 addresses within a single /18 prefix (193.27.128.0/18) and one IPv6 /48 prefix, with only one observed routing neighbour.
• This low neighbour count relative to the address inventory indicates an internal corporate estate for city administration, not a transit or access provider.

Notable

• The RDAP registrant Stadt Koeln and the AS handle StadtKoeln1 align directly with the operator's identity.
• The inventory consists of a single contiguous IPv4 block and one IPv6 prefix, consistent with a segmented internal network for a large municipal entity.
