About this network

One block, one neighbour, one netname, and every record agrees with every other.

What it's used for

• A company's own network. 4,096 addresses in a single IPv4 prefix, with one observed BGP neighbour and no IPv6 announced.

Notable

• 69.67.208.0/20 carries the netname GZSCI, registered to GZ Scientific Inc.
• The netname is identical to the handle the AS itself is filed under.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• This is the minimum viable autonomous system. One block, filed once, labelled with the same five-letter contraction everywhere, announced to one neighbour, and publishing nothing. Nearly all of the strangeness in this range comes from records touched repeatedly over decades by different people; a record touched once has nowhere to drift.
• Running an AS at all, rather than taking addresses from a provider, means somebody decided the network should be able to change providers without renumbering. That decision is usually made once and then never revisited, which is why so many single-block autonomous systems exist.
• Nothing answering a reverse lookup means nothing here is meant to be reached from outside. The addresses face outward for the company's own traffic.
• A /20 for one company is generous by present standards and unremarkable by the standards of when it was issued.
