In Route 53 console, there is a TTL input section that we can specify for a DNS record. I created a record with 86400 seconds and tried seeing the DNS from Cloud Shell using the dig url command, the TTL comes out as 300 seconds. I need help with the query please! ![Enter image description here](/media/postImages/original/IMgbsr80BDS3ms8KgKFCsU3g) ![Enter image description here](/media/postImages/original/IM2qvVBu9hRuG6WG-46MuR0g) ![Enter image description here](/media/postImages/original/IMen84s0HJTFuKBLJMs6KP9w) ![Enter image description here](/media/postImages/original/IMV5Ea5c9JQeiUeCLHZUEIcw)

Hi,

Do you query the origin DNS server via dig?

If you query an intermediate server between you the origin DNS (Route53 here), the TTL may have been overwritten by this one or any on the route up to the origin.

So, make sure that you query the DNS origin Route53 server to check the 86400. So, use @server option of dig: see https://linux.die.net/man/1/dig

Best,

Didier
