About this network

Every sampled address in four different blocks answers with the same reverse name, and that name is a sentence.

What it's used for

• Internet access in Ukraine. 12,288 addresses in four IPv4 prefixes, one IPv6 prefix, and 46 observed BGP neighbours.

Notable

• All twelve sampled addresses returned a name, and all twelve returned the same one: unassigned-please-contact-hostmaster.ukrhub.net.
• The samples span 212.90.160.0/19, 94.125.120.0/21, 94.176.196.0/22 and 185.151.104.0/22 — four separate allocations, one answer.
• Netnames run UA-UKRCOM-990720, UA-UKRCOM-20080814, UA-UKRCOM-20080827 and UA-UKRCOM-20160510.
• The IPv6 announcement is 2a04:42c0::/29.
• The AS handle repeats the number it belongs to: AS12593 - LLC "UKRCOM".

Interesting

• That reverse name is a wildcard record covering the whole zone, and somebody chose to make it useful. Instead of leaving addresses silent or naming them after the machine, the default answer tells anyone who looks that the address is spare and who to write to. Reverse DNS is one of the few channels where a network operator can leave a note for a stranger, and this is one of the few that uses it.
• The wildcard also means the sample proves nothing about which addresses are actually in use. A name that always answers is a name that never distinguishes.
• The reverse zone lives on ukrhub.net while the company is Ukrcom. The infrastructure domain and the trading name are different words, which is common enough that the reverse zone is often the first place a network's real internal name shows up.
