AS12655 announces 3 IPv4 prefixes covering 1,280 addresses and 2 IPv6 prefixes.

About this network

1,280 IPv4 addresses, a full IPv6 /29, and a reverse zone that names the business model out loud.

What it's used for

• Corporate connectivity for a directory and digital-marketing group. 1,280 addresses in three IPv4 prefixes, two IPv6 prefixes, and three observed BGP neighbours.

Notable

• 86.109.248.0/23 is netname IT2MEDIA-NET; 185.76.156.0/24 is DE-IT2MEDIA-20200219.
• Contacts include ODN Hostmaster and it2media-technik, while the holder is Sellwerk Verwaltungs GmbH.
• The IPv6 announcements are 2001:67c:14b8::/48, out of the registry's own assignment range, and 2a06:87c0::/29, a full allocation.
• Sampled addresses answer r2.lead-hub.de, nu.vhm-ibb.de and tb-delivery-1.it2media.de.

Interesting

• lead-hub is what the company sells, written into a hostname: sales leads, collected and distributed. Marketing infrastructure tends to be named with unusual candour because the people naming it are describing the product to each other rather than to the public, and reverse DNS is the one place that conversation becomes visible.
• Four unrelated brand names across three blocks and three hostnames, with a fifth on the holder line. Directory businesses are assembled by acquisition, and every acquisition leaves a name somewhere in the record.
• The address ratio is the modern one turned inside out: 1,280 IPv4 addresses against a /29 of IPv6, an allocation the size a national carrier would receive. One side is rationed and the other is not.
