About this network

512 addresses and 236 BGP neighbours, registered to one person.

What it's used for

• Interconnection. 512 addresses in two /24s, two IPv6 /32s, and 236 observed BGP neighbours.

Notable

• The registrant is Sandro Bolliger trading as Bolliger Network Solutions — a sole trader, named in full in the registry.
• Both /24s share netname CH-SBOLLIGER-20150930, one allocation split into two announcements.
• Two separate IPv6 /32s are announced, 2a06:8a00::/32 and 2a06:8a07::/32.
• The AS handle is RAVANA.

Interesting

• The ratio here is the most extreme kind this data produces. Two /24s is the smallest footprint an operator can hold and still be independently routed; 236 neighbours puts it in the company of national carriers. Whatever this network is for, it is not addresses.
• That is what an internet exchange makes possible. Join one, set your route server sessions to accept everyone, and your neighbour count becomes the size of the exchange rather than the size of your business. It costs one port and a membership fee, and a one-person operation ends up peering with more networks than most companies will ever route a packet to.
