Re: DNS Server
Interesting. I wonder what kind of garbage traffic they receive and why they want to analyse that.
Re: DNS Server
It's important for understanding how various types of denial of service attacks work. Some work now through techniques like DNS amplification, where attackers trick DNS servers into attacking a victim with lots of queries and traffic. Knowing how these queries are constructed helps in understanding how to mitigate this.
Over the years I've had many problems with ISP's DNS servers, so I've taken to just running my own recursive resolver that queries all the way to root servers if it needs to, completely bypassing the often unreliable ISP DNS servers, and caching responses so most name lookups are typically lightning fast if they are ones I commonly look up.
