About this network

The telecoms arm of the Koblenz municipal utility, selling access and colocation in the middle Rhine region.

What it's used for

• Residential, business and hosted connectivity. 58,880 addresses across 27 prefixes, five IPv6 announcements, and 116 observed BGP neighbours.

Notable

• The largest block, 5.231.128.0/18, is registered as KTK-DYNIP-NET — the dynamic address pool, named as such in the registry rather than only in reverse DNS.
• Reverse names for subscriber space are positional under ktk-ip.de. One sampled address breaks out into a different domain entirely: way2-gw01-colo-ko.nr-city.net, a colocation gateway with ko for Koblenz.
• Twelve dated netnames run from DE-KTK-990409 to DE-KTK-20121004, thirteen years of separate applications.
• Two IPv6 /32s, 2a01:5580::/32 and 2a02:1628::/32, plus three /48s.

Interesting

• Two /32s is one more than a provider is normally issued. RIPE gives a member a single allocation and expands it on request, so a second one usually arrives attached to a company that was bought rather than to an application that was filed.
• KEVAG is the Koblenz electricity and transport utility, and its telecoms subsidiary is the same municipal pattern seen across German networks: the organisation that already owned the ducts, the poles and a billing relationship with every household in town turned out to be well placed to sell them internet access as well.
