About this network

Three company names across one small record, and the oldest one is still doing the work.

What it's used for

• A German regional internet provider. 12,288 addresses across two IPv4 prefixes, one IPv6 prefix, and 103 observed BGP neighbours.

Notable

• The inventory is 213.182.0.0/19 and 46.35.48.0/20, plus 2001:14e0::/32.
• Both netnames are DE-SPEEDKOM-, dated 19991220 and 20141024.
• The contacts mix the two names: IRT-SPEEDKOM1 and Netmaster SpeedKom alongside the current company and its abuse desk.
• One of six sampled addresses returned a name: dyn3-254.backbone-24.de.

Interesting

• A fifteen-year gap separates the two netnames and both still say the former company name. The 2014 registration reused the older label rather than the current one, so a company that renamed itself kept filing under the name it had left behind. Registry conventions inside an organisation outlive the branding decisions above them.
• The one reverse name belongs to a third domain, matching neither company. Regional providers accumulate domains the way they accumulate address blocks, and the one serving reverse DNS is usually whichever was configured first and never revisited.
• dyn3-254 marks a dynamically assigned address. Naming dynamic ranges explicitly is what providers do so that receiving mail servers can treat them appropriately, and it is a small courtesy that costs nothing and saves a lot of argument.
• 103 neighbours behind 12,288 addresses is a network whose value is its interconnections. Regional German providers peer heavily because the exchanges are close and the transit is not.
