About this network

Five blocks, one netname, and the registrant on every one of them is the word unknown.

What it's used for

• A packaging manufacturer's network. Five IPv4 prefixes announced from Sweden, no IPv6, twelve thousand five hundred and forty-four addresses, across six observed BGP neighbours.

Notable

• All five blocks share a single netname, and it joins the first word of the group's brand to the name of the other company in the group rather than naming either in full.
• Every block's registrant field reads as not known. There is no company contact, no technical contact and no abuse contact anywhere in the record.
• All five announcements come out of one contiguous range, which is what a single early allocation looks like when it is later split for routing.
• The holder name puts the abbreviation for a public company in front of the brand rather than after it.
• Fifteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Blocks with no contacts at all are legacy space: assigned before the registry required registration records, and never brought under a membership agreement afterwards. They work perfectly and answer to nobody.
• A manufacturer holding twelve thousand addresses and publishing no reverse names has decided the network should be invisible from outside. Nothing here is meant to be found; it is meant to reach out.
