The recommended TTL value depends on how frequently you anticipate changing the DNS records. Shorter TTLs (e.g., 300 seconds or 5 minutes) allow for faster propagation of changes but increase DNS query load. Longer TTLs (e.g., 3600 seconds or 1 hour) reduce DNS query load but increase the time it takes for changes to propagate. A common starting point is 300 seconds for subdomains that might need frequent updates, and 3600 seconds for subdomains with stable configurations. Consider your specific needs and adjust accordingly.
