This runbook updates the Time-to-Live (TTL) value for specified DNS records in AWS Route 53. Increasing the TTL can reduce the frequency of DNS lookups, thereby potentially improving DNS resolution time and reducing costs. However, a longer TTL may also mean slower propagation of changes.

This task fetches DNS records in AWS Route 53 with a TTL value less than a specified number of hours. Identifying records with low TTL can help in optimizing DNS query costs and performance. A lower TTL means more frequent DNS queries, which could lead to higher costs and increased load on the DNS servers.
