About this network

A number issued in the registry's early years, holding address space registered more than a decade later.

What it's used for

• A university's campus network. A single IPv4 prefix announced from Iran, no IPv6, one thousand and twenty-four addresses, through two observed BGP neighbours.

Notable

• The holder field opens with the institution's name abbreviated to two letters and a place, in mixed case, then writes the same name out in full. The abbreviation and the expansion sit side by side.
• The AS handle is that abbreviation alone, in capitals, which makes it the only field in the record that says nothing about what kind of organisation this is.
• The netname is a country code, the same abbreviation, and a full date. That date is far more recent than the number itself, so the addresses were registered long after the number was set aside.
• The block is registered to the university and an abuse role, with nothing else attached.
• Two upstreams for a thousand addresses is redundancy rather than capacity.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• The gap between an early number and late address space is a common shape in this range. Numbers were handed out freely when they seemed plentiful; addresses were rationed, and a university waited for them.
• A campus that publishes no reverse names is not hiding anything. It is a network where the people who need to find a machine already know its name, and everyone else is asking from outside.
