AS14773 — LANLEB-IU13

AS14773 announces 1 IPv4 prefixes covering 4,096 addresses and 2 IPv6 prefixes.

About this network

A school service agency with 29 BGP neighbours and 20 IPv6 prefixes cut into a descending staircase.

What it's used for

• A regional education service agency's network. 4,096 addresses in a single IPv4 prefix alongside 20 IPv6 prefixes, with 29 observed BGP neighbours.

Notable

• 206.82.16.0/20 carries the netname LAN-LEB-IU-13, registered to the agency.
• The IPv6 announcements run 2620:1d5::/39, 2620:1d5:200::/39, 2620:1d5:400::/38, 2620:1d5:800::/38, 2620:1d5:c00::/39, 2620:1d5:e00::/40, 2620:1d5:f00::/41, 2620:1d5:f80::/42 and onward, each smaller than the last.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• That staircase is one allocation taken apart the way binary arithmetic requires. Covering a range that is not a power of two forces exactly this pattern: halve, halve again, and keep halving until the remainder is covered. Every operator who has ever announced an odd-sized range has produced the same shape, and every one of them has been asked by an upstream why they cannot just send one route.
• 29 neighbours is an extraordinary number for an organisation whose job is supporting school districts, and it says the agency is the routing hub for those districts rather than a customer of one. Public education builds its own regional carriers because commercial ones will not serve the rural half of a county at a price a district can pay.
• The IPv6 footprint dwarfs the IPv4 one, which is the correct shape for a network built after the addresses ran out and unusual for one that predates it.
