About this network

An Israeli carrier whose IPv6 announcements double in size, block after block, tiling a /38 exactly.

What it's used for

• Internet access and transit. 45,824 addresses in 79 IPv4 prefixes, 28 IPv6 prefixes, and 128 observed BGP neighbours.

Notable

• The IPv6 prefixes run 2a02:ba0::/47, 2a02:ba0:2::/47, then /46, /45, /44, /43, /42, /41, /40, /39 — each one twice the size of the last.
• Added together, those ten blocks cover 2a02:ba0::/38 with nothing left over and nothing overlapping.
• Several netnames read IL-IPPLANET-20001218 and IL-IPPLANET-20021004, naming a company that is not the current holder.
• Reverse names are the address itself with the domain appended: 62.56.130.0.gilat.net.

Interesting

• That doubling ladder is what you get when a range is expressed as CIDR blocks starting from an address that is not aligned to its own size. Each step covers what is left, and each step can be twice the previous one, so the arithmetic produces a staircase. It is the most legible piece of binary in this entire dataset.
• IPPlanet was the satellite broadband business Gilat ran before the telecoms arm took the name, and the netnames still carry it with the dates the blocks were issued. Two of them are 2000 and 2002, which is the satellite era preserved in a database.
• Writing the address forwards in the reverse name, rather than backwards as the zone file has it, means somebody wrote a generator that flips it back. Most do not bother.
