About this network

16,384 addresses in one unbroken block, behind two BGP neighbours.

What it's used for

• A German internet and hosting provider. 16,384 addresses in a single IPv4 prefix, one IPv6 prefix, and two observed BGP neighbours.

Notable

• The entire IPv4 inventory is 213.252.0.0/18, announced whole rather than split.
• Its netname is DE-CU-990917, using a two-digit year.
• The IPv6 prefix is 2a04:d740::/29.
• One of three sampled addresses returned a name: 255.ekm.de.

Interesting

• A /18 announced as one prefix is unusual and it is a choice. Most providers this size carve their space into smaller announcements to steer traffic between uplinks. Announcing the whole block says routing policy is handled somewhere other than the routing table.
• The netname says CU and dates to 1999, matching neither the current company name nor its registered abbreviation. The block outlived whoever first requested it, and the netname is the only surviving reference to them.
• 255.ekm.de is about as short as a reverse name gets. The domain is not the provider's own, and the label is just the last octet, which is the pattern you see when a customer runs their own reverse zone on delegated space.
• The IPv6 prefix is a /29, eight times the /32 an operator normally receives. Behind two neighbours and a single IPv4 block, that size reflects the registry's policy for what a provider may request rather than anything about this network's scale.
