AS12591 — SMARTCOM

AS12591 announces 1 IPv4 prefixes covering 512 addresses and 1 IPv6 prefixes.

About this network

512 IPv4 addresses and an IPv6 /48 handed out directly by the registry rather than by a provider.

What it's used for

• Connectivity in Bulgaria. 512 addresses in a single IPv4 prefix, one IPv6 prefix, and two observed BGP neighbours.

Notable

• The IPv4 inventory is one /23, 193.178.152.0/23, netname SMARTCOMBG.
• The IPv6 announcement is 2001:67c:2154::/48.
• The AS handle is SMARTCOM, while the registered holder is SMARTCOMBG Smartcom Bulgaria AD.
• First seen in routing data in March 2001, a real date rather than the floor of the archive.
• Three sampled addresses were queried and none returned a name.

Interesting

• 2001:67c::/32 is the registry's own block, carved into /48s for networks that want addresses tied to themselves rather than to an upstream. Holding one means going to the registry, justifying the request and paying for it, instead of accepting a slice of a provider's allocation. It buys a small piece of independence, and it is the second such /48 in this stretch of the number range.
• The IPv6 block is a /48 and the IPv4 block is a /23. In address count those differ by more digits than anyone has use for, which is the point of the transition: IPv6 sizes are chosen by how many networks you need, not how many machines.
• 512 addresses, two upstreams, a real 2001 first-seen date. A quarter-century-old network that never grew is a different thing from a new one that never will.
