About this network

36 scattered announcements including one block the registry itself manages and one registered to a London company.

What it's used for

• Internet access and hosting in Sofia. 14,848 addresses in 36 IPv4 prefixes, one IPv6 prefix, and 104 observed BGP neighbours.

Notable

• 87.246.6.0/23 carries the netname RIPE-NCC-MANAGED-ADDRESS-BLOCK.
• 87.246.12.0/22 is netname M247-LTD-London, with GLOBALAXS NOC as its contact.
• 83.222.178.0/23 is CKYLINK10GCN.
• The company's own blocks are dated BG-GCN-20050825, BG-GCN-20070702 and BG-GCN-20090827.
• The 36 announcements average around 400 addresses each, mostly /23s and /24s spread across five separate /8s.
• Eighteen sampled addresses were queried and none returned a name.

Interesting

• A netname reading RIPE-NCC-MANAGED-ADDRESS-BLOCK means the registry is holding the record itself rather than a member holding it. That happens to space that was reclaimed, is in dispute, or was left behind when a member ceased to exist. Somebody is still announcing it, which is a different question from who is entitled to.
• A London company's netname on a Bulgarian network's block is the ordinary machinery of the address market: blocks are leased and sublet, and the registry entry keeps naming the party who holds the paperwork long after the routing has moved on.
• Thirty-six pieces for fifteen thousand addresses is what an inventory assembled from many small acquisitions looks like. None of it aggregates, so all 36 routes travel to every router on the Internet.
