About this network

The capitalisation of the netname changes at the registry boundary.

What it's used for

• A media company's network. 1,536 addresses across six IPv4 prefixes drawn from three separate ranges, six observed BGP neighbours, and no IPv6 announced.

Notable

• Four blocks are all capitals: DISNEY-SPN-PPC, DISNEY-STUDIO-EAST, DISNEY-SPN-1, DISNEY-SPN-2.
• Two are mixed case: Disney-SPN-NY2 and Disney-SPN-UK, and both name only roles as their registrant, with no organisation given.
• DISNEY-STUDIO-EAST is registered to a subsidiary studio under its own name.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• The all-capitals blocks and the mixed-case ones come from two different regional registries. One normalises identifiers to capitals and the other preserves what was typed, so the shape of the string tells you which side of the world the record was created on without reading the country.
• The two records that name no organisation list a maintainer and technical and abuse roles instead. That is the other registry's model: the object is owned by a maintainer key, and the company behind it is one indirection away.
• A studio subsidiary holding a /24 in its own name, inside a parent's autonomous system, is an acquisition whose address records were never folded into the parent's.
