About this network

A university on 8,192 addresses reached through exactly one neighbour.

What it's used for

• The campus network of a private Turkish university. 8,192 addresses in a single IPv4 prefix, one observed BGP neighbour, and no IPv6 announced.

Notable

• The whole inventory is 159.20.64.0/19, netname TR-SABANCIUNIVEDU-20110909.
• The registry lists the university itself alongside a generic abuse role.
• First observed in the routing archive in August 2000.
• Three addresses were sampled and none returned a name.

Interesting

• Universities almost always reach the internet through a national research and education network rather than through commercial providers, and one neighbour is what that looks like from outside. The single upstream is a shared academic backbone, and everything the campus reaches goes through it.
• The netname carries a 2011 date while the AS has been announcing since 2000. The record was rewritten at some point, most likely when the block moved between registry objects or the university took direct responsibility for it. Dates in netnames record paperwork events, not the age of the network.
• A /19 for one campus is generous by current standards and unremarkable for its era. Universities were among the earliest requesters of address space and received allocations sized for a future where every device had a public address, which is why campus networks still have room that newer organisations of the same size cannot obtain.
• No IPv6 announced, from an institution whose research departments are the usual place to find it deployed first.
