Nxdomain redirect revenue
by Cameron Byrne 04 Oct '11

04 Oct '11

Just an fyi for anyone who has a marketing person dreaming up a big nxdomain redirect business cases, the stats are actually very very poor... it does not make much money at all. It is very important to ask the redirect partners about yields... meaning, you may find that less than 5% of nxdomain redirects can be actually served an ad page because 95%+ of nxd are printer lookups and such that cannot be served an ad page. Then from that less than 5% pool, the click through rates are around 1% Net net, no free money of any meaningful value. But, ymmv... but I don't think by much. Cb

Re: Over a decade of DDOS--any progress yet?
by alvaro.sanchez＠adinet.com.uy 04 Oct '11

A very common action is to blackhole ddos traffic upstream by sending a bgp route to the next AS with a preestablished community indicating the traffic must be sent to Null0. The route may be very specific, in order to impact as less as possible. This needs previous coordination between providers.

It's updates, I've got a 1511+ here and at the office. It phones home to check for updates. I noticed this the day I got it. Blocked the dst IP and that was the only thing that "broke".
