About this network

A gym chain's network, on carrier IPv4 addresses and its own IPv6 allocation.

What it's used for

• Corporate and club connectivity. 512 addresses in one IPv4 /23, one IPv6 /36, two observed BGP neighbours.

Notable

• The /23 is not the company's. 63.64.130.0/23 is netname UUNET63, registered to Verizon Business and UUnet Technologies.
• The IPv6 announcement, 2620:1fb::/36, is a direct assignment out of ARIN's range for end users.
• Two neighbours for a chain with hundreds of locations.

Interesting

• The two address families came from different decades and different arrangements. The IPv4 space is UUNET's, assigned when UUNET still existed as a company and inherited by Verizon through the acquisitions that followed. The IPv6 space is the company's own, obtained directly. A business that could not get portable IPv4 without buying it had no trouble getting portable IPv6.
• A /36 is 4,096 /48 networks — one for every club several times over. Nothing about the IPv4 side of this network suggests that kind of headroom, which is the point: IPv6 policy was written so that the sizing conversation would never need to happen again.
