Unbound is particularly good for this because you can configure it to populate your cache with responses before you even ask for them (kind of).
Essentially if you do a DNS lookup and the result is in the cache, it returns the cached result straight away. It will then check to see if the response is due to expire from the cache soon, and if it is, then it will refetch it at that point. So if you visit a site regularly, it should always be in your cache.
- dfc 12y agoHow useful is prepopulating a DNS cache on a home network? How often do you expect OP is going to reboot the caching dns box?
- X-Istence 12y agoDNS records contain an expiry, unbound will go update the record so that the expiration never reaches 0. This can be very handy even on a home network, as you avoid the whole WAN trip to fetch records for sites you visit often, such as Google and others.
