AS12663 — VODAFONE-GROUP

AS12663 announces 156 IPv4 prefixes covering 453,376 addresses and 2 IPv6 prefixes.

About this network

461,312 addresses in 263 announcements, under a netname dated June 1993 — the oldest in this sweep.

What it's used for

• Carrier connectivity in Italy. 461,312 addresses in 263 IPv4 prefixes, two IPv6 prefixes, and one observed BGP neighbour.

Notable

• 145.230.128.0/17 and 145.230.32.0/19 carry the netname DE-VODAFONE-19930609.
• Other netnames run DE-VODAFONE-971003, DE-VODAFONE-20100721, DE-VODAFONE-20101209 and DE-VODAFONE-20111223.
• Every netname begins DE-, while the holder is Fastweb SpA and the blocks are announced from Italy.
• The IPv6 side is two /44s, 2a01:818:1000::/44 and 2a01:818:1060::/44.
• Eighteen sampled addresses were queried and none returned a name.

Interesting

• A 1993 allocation date is the earliest anywhere in this range. It predates the commercial web and most of the companies in this number range, and it is attached to a block that is still carrying traffic thirty-three years later. Address registrations outlive nearly everything else in the industry.
• The country prefixes disagree with reality. German netnames on Italian announcements are what happens when a multinational holds its address space centrally and lets each national operating company announce whichever pieces it needs. Reading netname prefixes as geography fails on exactly these networks — the large ones.
• Two /44s of IPv6 against 461,312 IPv4 addresses is a striking imbalance for a carrier this size, and the opposite of the pattern in the smaller networks nearby, where IPv6 holdings dwarf IPv4.
