About this network

All six blocks share one netname and one allocation date, down to the day.

What it's used for

• A regional technology company's network. Six IPv4 prefixes announced from Italy, no IPv6, four thousand six hundred addresses, across three observed BGP neighbours.

Notable

• Every block carries the identical netname, ending in the same allocation date, so all six are pieces of one original grant rather than separate acquisitions.
• Five of the six fit together end to end with no gap between them, covering four thousand consecutive addresses that could be announced as a single route.
• The sixth sits apart from the rest, a /23 further up the same range.
• Registrants are the company and its network administration role, with no third party anywhere.
• Eighteen addresses were queried for reverse DNS and none returned a name.
• No IPv6 is announced at all.

Interesting

• Splitting one contiguous grant into five routes adds four entries to every routing table on earth and gives the operator per-piece control over which upstream carries what.
• Twenty-five years of routing history on a network that still announces no IPv6 is a common pattern for organisations whose users are internal and whose address needs stopped growing.
• One netname on six blocks is unusually tidy for a registry record. Most holders this size have collected at least one inconsistent entry.
