New on RIPE Labs: Operator Level DNS Hijacking
by Mirjam Kuehne 11 Jul '16

11 Jul '16

Dear colleagues, Please find a new article by Babak Farrokhi on RIPE Labs: Operator Level DNS Hijacking This is follow-up from Babak's recent research on DNS hijacking. In this new article he is wondering whether this is a common practice among the operators. With the help of RIPE Atlas, he started to think of a solution to figure out whether such practice is widespread in other areas of the world. https://labs.ripe.net/Members/babak_farrokhi/operator-level-dns-redirection… Kind regards, Mirjam Kuehne RIPE Labs

Question about use of cname in Google's services
by Anurag Bhatia 04 Jun '16

04 Jun '16

Hello everyone Someone asked me question on why google uses cname for their services anyways? I mean I get it that for Google Apps customers it makes sense to have mail.domain.com pointed to a cname rather then A record to a host which may die. But why for their own services? Like e.g "mail.google.com" is cname to googlemail.l.google.com. and googlemail.l.google.com. eventually returns A record. This adds up one extra step in resolution and I wonder why Google does it this way? What advantage they get ? or What advantage they miss if they simply return record which I am getting for googlemail.l.google.com. directly as A record for mail.google.com ? Curious to hear your thoughts. Thanks! -- Anurag Bhatia anuragbhatia.com

New on RIPE Labs: Anycast vs. DDoS - Evaluating the November 2015 Root DNS Event
by Mirjam Kuehne 31 May '16

31 May '16

Dear colleagues, IP anycast has been widely used to replicate services in multiple locations as a way to deliver better performance and resilience. It has been largely employed by CDNs and DNS operators, such as on the root server system. However, there is little evaluation of anycast under stress. Please find this short guest post by Giovane Moura on RIPE Labs: https://labs.ripe.net/Members/giovane_moura/anycast-vs-ddos-evaluating-the-… Kind regards, Mirjam Kuehne RIPE NCC
