About this network

A German IT services house announcing one IPv4 block registered to a company it used to be.

What it's used for

• Managed hosting and business connectivity. 8,192 addresses in a single /19, one IPv6 /29, and two observed BGP neighbours.

Notable

• The one IPv4 prefix, 212.101.192.0/19, is netname DE-ICSMEDIA-990520 — a 1999 allocation under a different name — with DTS Systeme Muenster listed as the current registrant.
• The IPv6 allocation is 2a06:7880::/29, announced whole and not split.
• Two neighbours against 8,192 addresses.

Interesting

• A /29 is an enormous amount of IPv6 for a company with one IPv4 /19. It is the size a regional registry hands to an operator expected to assign onward to customers, which says more about what this business does than the address count does: managed hosting means somebody else's servers, each needing their own space.
• Announcing that /29 as one prefix is the opposite of what most operators do with IPv6, and it is the tidier choice. Every extra route is carried by every router on the internet, and a network with two upstreams has no traffic engineering reason to publish more than one.
