re: Explain DNS TTL Like I'm five VIEW POST


Let's say you want to make a phone call to Bob, but you don't know his cell number. Luckily you have this phone book which say Bob's phone number is +1 XYZ 999 001. But what if Bob want change his number? How to decide should I buy or update phone book each day/month/year to know for sure that I will find most actual records there? In other words TTL is the interval you can trust that Bob's phone record will be consistent with Bob's most recent cell number.
