About this network

Eighty-two neighbours behind a single block of a thousand addresses.

What it's used for

• A small company's network. One IPv4 /22 announced from Poland, no IPv6, one thousand and twenty- four addresses, across eighty-two observed BGP neighbours.

Notable

• Eighty-two connections for one block is one of the highest ratios of neighbours to addresses in this part of the number range.
• The registrant is a trading name followed by an individual's, so the company and the person running it are the same entry.
• The netname is the trading name alone, with no country code, date or sequence number.
• No IPv6 is announced despite the connection count.
• Three addresses were queried for reverse DNS and none returned a name.

Interesting

• A thousand addresses and eighty-two neighbours means the routing is the asset. Networks shaped like this are usually at an exchange point, peering with everyone present because it costs almost nothing to do so.
• A netname with no date is one nobody expected to need a second of. It has stayed unique because there is only ever one block.
• A one-person company holding its own AS number and peering this widely is a reminder that independence in routing costs paperwork rather than scale.
