I want to gather some statistics on TTL of certain NS records. When
I'm using 'dig' command (e.g. 'dig com. NS') several times I'm getting
cached decreasing TTL values. I've tried to clear the local DNS cache
with 'lookupd -flushcache', but it did not . Is there is a way to
get an original TTL for a given domain name?
