Hi, all.
I have one question about NS cache ttl.
for example, I can get two different NS TTL like below.
$ dig google.com ns +trace
google.com. 172800 IN NS ns2.google.com.
google.com. 172800 IN NS ns1.google.com.
google.com. 172800 IN NS ns3.google.com.
google.com. 172800 IN NS ns4.google.com.
;; Received 164 bytes from 192.5.6.30#53(a.gtld-servers.net) in 173 ms
google.com. 345600 IN NS ns4.google.com.
google.com. 345600 IN NS ns1.google.com.
google.com. 345600 IN NS ns2.google.com.
google.com. 345600 IN NS ns3.google.com.
;; Received 164 bytes from 216.239.34.10#53(ns2.google.com) in 43 ms
so, on resolving DNS, which NS record TTL will be cached generally?
172800 or 345600?
Thanks in advance.
