About this network

Two /21s of DSL subscribers answering on a domain that is not the company's name.

What it's used for

• Residential internet access. 4,096 addresses in two /21s with one observed BGP neighbour and no IPv6 announced.

Notable

• Both sampled addresses answered as pppoe-176-107-205-254.lekks.ru and pppoe-178-217-125-254.lekks.ru, on a domain unrelated to the registered company name.
• The two blocks carry netnames BORISLTD-NETWORK and ASBORISLTD — the same name arranged two different ways.
• One of them puts AS in front, in a field that has nothing to do with autonomous systems.
• First seen in routing data in April 2011.

Interesting

• pppoe in the host name is the access method showing through: sessions established over Ethernet the way they once were over telephone lines, with a username and password per subscriber. It is how most DSL and much fibre still authenticates, decades after the dial-up it was modelled on stopped existing.
• The trading name in DNS differing from the registered name is the ordinary gap between what a company is called on its invoices and what customers see. The registry records the entity; the reverse zone records the brand.
• One upstream for four thousand subscriber addresses is a small ISP with a single point of failure, which is a business decision rather than an oversight when the alternative costs money every month.
