Is it possible to "prevent" poisoning attacks? Is it beneficial, or even possible, to prevent TTL's from being an excessively high value?
It would be very interesting in seeing the difference in DNS traffic for a domain if it sets TTL to let's say 600 seconds or 86400 seconds. This could perhaps be used as a metric in trying to figure out the impact of capping the TTL? Anyone know if anyone did this on a large domain and have some data to share?
If one had to repeate the cache poisoning every 10 minutes I guess life would be much harder than if you had to do it once every day?
