I was interested and searching about the size of a DNS request to have some idea if on a satellite or slow link with limited downloads.
After running the dig command on a few sites I looked at the results the delay is very low from have understood it to be from another program.
The delay from my PC to the Pi is 3-4 mS its WIFI.
Once it is in the cache its 5-6 mS to complete the request with nearly 1 million being in blocklist.
