About this network

The reverse zone labels which addresses are the network and broadcast ones, in capitals.

What it's used for

• A business provider. Twelve IPv4 prefixes and one IPv6 /32 announced from the United Kingdom, seventy-nine thousand eight hundred and seventy-two addresses, across eighty-eight observed BGP neighbours.

Notable

• All eighteen queried addresses answered. The first address of each range is named with the word for a network in capitals, the last with the word for a broadcast, and both use only three of the four numbers.
• Ordinary addresses in between get all four numbers in lower case, so the zone marks the two addresses in every range that cannot be used.
• One address answers as a mail server on a customer's own domain, the single exception in the sample.
• Eleven netnames share a country code, the brand and a date, and the dates run from the late nineteen-nineties to well into the following decade, one or two a year.
• The twelfth uses different initials with a much later date, from an acquisition or a separate service.
• Eighty-eight neighbours for eighty thousand addresses.

Interesting

• Publishing the network and broadcast addresses by name is unusual and genuinely useful. Anyone scanning or diagnosing can see the boundaries of each customer range without guessing at the prefix length.
• A provider that has collected a block almost every year for two decades has a different shape from one that bought a large allocation early. The address space is a record of continuous sales rather than a single bet.
