google-public-dns not set “max-cache-ttl” ?
As a test,I create a record: ttltest.slhy.net,set ttl to 99999999,
other name server ’s response ttl is 604800 (7 days),but google-public-
dns-a.google.com and google-public-dns-b.google.com answer is actual:
99999999. I think the google’s public dns not set "max-cache-ttl"
option as bind 9. this may make longer "dns cache poison".
