About this network

More than a thousand observed neighbours on twenty thousand addresses.

What it's used for

• A provider's network. Twelve IPv4 prefixes and one IPv6 /30 announced from Italy, twenty thousand addresses, across one thousand and forty-three observed BGP neighbours.

Notable

• The neighbour count is more than a thousand, which is four times as many connections as the network has blocks of a hundred addresses.
• Every netname follows one scheme without exception: country code, company name, allocation date, with dates spanning thirteen years.
• The registrant list flips order between blocks, naming the company first on some and its technical staff first on others, which is the only inconsistency in the record.
• The IPv6 prefix is a /30, larger than the allocation most member organisations hold.
• One block's registry lookup failed, so its details are unknown rather than absent.
• Eighteen addresses were queried for reverse DNS and four returned a name.

Interesting

• All four answering names put the octets in reverse order behind a word meaning host, so the address reads backwards out of its own hostname. One of them ends in the last value of its range and is named like any other machine.
• A thousand neighbours puts this network among the most connected in its whole number range, and the address count says none of that is for its own traffic.
• Thirteen years of allocations under one naming scheme means the same person or the same template has filed every request since the beginning.
