Hello MichaelPro,<br />
<br />
My O'Reily book on DNS &amp;&nbsp;Bind appears to imply that the maximum TTL is 99,999,999 seconds. Approximately 3.1 years. Either that or 3,600,000 seconds, approx. 41 days. To know for definite, I would suggest reading the RFC's.<br />

What is the maximum TTL Value i can set for DNS Entries? Such as A, MX, CNAME ?<br />
<br />
I'm more interested in an article describe it in more detail than just a number but either one would work. <br />
<br />
thanks,

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Transmission Control Protocol/Internet Protocol (TCP/IP) is the set of networking protocols that define end-to-end connectivity specifying how data should be packeted, addressed, transmitted, routed and received at the destination. This functionality is organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.

TCP/IP

The Domain Name System (DNS) is a hierarchical, globally distributed system responsible for associating the name of a computer, service or other resource into an IP address for connecting to the Internet or a private network. Most prominently, it translates domain names to the numerical IP addresses needed for the purpose of computer services and devices worldwide.
