Output: vec

Output: what is dns propagation and how does ttl affect how quickly changes are visible

Output: hyde

Output: DNS propagation is time for changes to spread through cached resolvers worldwide. TTL (Time To Live) controls cache duration. High TTL (86400s) means up to 24h wait. Before changes, lower TTL to 300s, wait for old TTL, make change, then restore TTL. Use dig @8.8.8.8 domain.com to check Google's view. Full propagation can take 24-48h for high-TTL records.
