AS13760 — UNITI-FIBER

Network type: residential

AS13760 announces 81 IPv4 prefixes covering 167,168 addresses and 22 IPv6 prefixes.

About this network

An IPv6 ladder descends by halves, skips one piece, then jumps back up to a larger one.

What it's used for

• A wholesale fibre and transit carrier. 142,336 addresses across 108 IPv4 prefixes, 20 IPv6 prefixes, and 160 observed BGP neighbours.

Notable

• Under 2607:fb00 the announcements run /43, /44, /45, /47, /48 and then /46, so the sizes fall and then rise again.
• Adding those up leaves a single /48-sized hole in the middle of the range that is never announced.
• 204.28.64.0/19 is netname MONROE, registered to a city school board rather than the carrier.
• Netnames SL-18-IPV4-1 and SL-18-IPV4-2 carry initials that match nothing in the registrant.
• 2600:4c01:ffff::/48 sits at the very top of its parent block.
• First seen in the routing archive on 2000-08-25, a real date a week after the archive begins.

Interesting

• The gap in the ladder is the interesting part. A network splitting a block by halves produces an unbroken sequence; this one produces a sequence with a piece missing, which means that piece is delegated somewhere else, held back, or simply forgotten.
• A school board's block announced inside a carrier's AS is the wholesale business showing through. The carrier moves the traffic and the customer keeps the registry entry.
• 160 neighbours against 108 prefixes is a network whose product is interconnection rather than address space.
