About this network

The reverse names are the access protocol's own name, under two unrelated domains.

What it's used for

• An internet provider. Fifteen IPv4 prefixes and one IPv6 /29 announced from Ukraine, ninety-six thousand addresses, across twenty observed BGP neighbours.

Notable

• Three answering addresses return names whose first label is the dial-up-descended access protocol used to authenticate broadband subscribers, spelled with its usual mixed capitals.
• Two of those names sit under the provider's brand domain and one under a different domain entirely, three letters that appear nowhere else in the record.
• Six blocks carry a bare netname of country code plus company name; seven more add the allocation date, and those dates span nearly two decades.
• The largest announcement is a /16, sixty-five thousand addresses in one route.
• Eighteen addresses were queried for reverse DNS and three returned a name.

Interesting

• A protocol name as a hostname tells you how subscribers connect but nothing about which subscriber it is. That is a reasonable privacy outcome reached for engineering reasons rather than policy ones.
• The second domain is the more useful signal. It suggests a network absorbed from another operator whose reverse zone came along with the addresses.
• The AS handle names a brand that the registrant does not, so the company trades under one name and registers under another.
