I believe you but don't see where your link mentions Cogent. As James says, the user's IP address would help, but needs to be by PM to one of us rather than posted in public.
You have to prowl around the RIPE interface, which I wasn't familiar with, so many thanks to jpm for the link. You can see which other Autonomous Systems the ISP peers with using BGP which is how the core of the internet works. (ISP to ISP).
You can even see which IPv4 and IPv6 space they announce, so the customer will most likely be on one of these v4 ranges:
193.17.176.0/23
193.17.87.0/24
193.17.86.0/24
Cogent Communications are a huge international ISP transit, linking lots of ISPs together. A small ISP will only link to one transit partner. The AS neighbours shows only "1 left, 0 right, and 1 unique" which shows the scale of the operation. Contrast to other ISPs networks.
In the lower right you can open up the WHOIS section, and the "Other Values" and it shows that this AS links to AS174. They accept anything from 174 and 174 announces them, so 174 is the parent. AS174 is Cogent Comms.
Pretty much answers my questions, maybe not others. Small regional ISP whom has just started. May be able to scale as they gain customers.
