AS12608 — DATALABS-TRANSPORT-AS

Network type: hosting

AS12608 announces 1 IPv4 prefixes covering 256 addresses and 1 IPv6 prefixes.

About this network

An AS number twenty years older than the addresses it carries, holding 256 IPv4 addresses and a full-size IPv6 allocation.

What it's used for

• Connectivity in Czechia. 256 addresses in a single IPv4 prefix, one IPv6 prefix, and two observed BGP neighbours.

Notable

• The IPv4 inventory is one /24, 89.207.155.0/24, netname CZ-IGLGNETWORK-20230918.
• The IPv6 announcement is 2a13:3300::/29, a full registry allocation out of a range only recently opened.
• First seen in routing data in July 2003, twenty years before the netname date on its address block.
• The registered holder handle is IGLG-7F5-DATA while the AS handle is DATALABS-TRANSPORT-AS.
• Three sampled addresses were queried and none returned a name.

Interesting

• The two halves of this network are wildly mismatched in size, and that mismatch is the whole story of address policy in 2026. The IPv4 side is 256 addresses, the smallest block that can be routed at all. The IPv6 side is a /29, the same class of allocation held by networks hundreds of times larger, because IPv6 space is issued by need rather than rationed by scarcity.
• An AS number in the routing table since 2003 with an address block registered in 2023 means the number outlived whatever it originally announced. AS numbers are durable identifiers that survive changes of owner, business and address space, so a first-seen date says when the number started being used, not when this network began.
• Two unrelated names on one record, one of them containing a hex-looking fragment, is a registry entry edited by more than one generation of administrator.
