I added bunch of static DNS entries (with the help of great scripts) and it seems to have worked well.

But I notice that the DNS Cache includes the static entries (marked with an S) but with a TTL that appears to be 1 second.

I recorded a video of the TTL going from 1 to 0 and then repeating.

What is going on with this? Is this normal?
