IP address

[tahoe]

A customer asked me a question that I don't have the answer...

 

He said that Charter changes his router IP address from time to time. He feels that it will mess up remote access to the ISY. I was thinking that it didn't matter if the Charter modem IP address changed.

 

Whats the right answer???

Hi tahoe,

 

If the IP address changes regularly, then he might not have access to ISY unless he uses dynamic DNS to map the ip to a name. In short, he might be going to the wrong IP!

 

With kind regards,

Michel

Depends upon your definition of "mess up"

If the IP address changes, nothing in the house will break.

But if you are away from home, and don't know the new IP address, you will be extremely frustrated.

 

Using a dynamic DNS service (like Michel mentioned, many good free ones) eliminate this problem by giving you a permanent name to get to your house. You would need a client that will detect and notify the dynamic DNS service whenever your IP changes.
