About this network

Eight prefixes carrying three generations of a newspaper group's name.

What it's used for

• Corporate networking for a British newspaper publisher. 3,584 addresses across eight IPv4 prefixes, five observed BGP neighbours, and no IPv6 announced.

Notable

• Seven of the eight blocks sit in 213.165; the largest is 195.234.240.0/22.
• The netnames disagree about who owns them: ASSOCIATED-NEWSPAPERS-LTD, UK-ASSOCIATED-19991228 registered to Associated Newspapers Limited, DMGT-16, and DMG-Media-Limited-t2.
• Eighteen addresses were sampled and none returned a name.

Interesting

• Three names for one company sit in this inventory: the newspaper business it started as, the holding-group initials, and the current media brand. Each was current when its block was filed, and the registry keeps all of them because a netname is written once. The corporate history is legible in the order the address space was acquired.
• Eight prefixes for 3,584 addresses, seven of them adjacent in the same /19-sized neighbourhood, means space assigned piecemeal over years rather than in one allocation. A publisher's network grows by projects — a new site, a new title, a new data centre — and each one asks for a little more.
• Five neighbours is more upstream diversity than a corporate network usually carries. For a publisher, the front page being unreachable is the outage that matters, and the cheapest insurance against it is another provider.
