Permanence of WAN IP addresses and names

RB42
I've Been Here Awhile

I can access my home network from elsewhere via either of these:

    CPEa45XXXXXX9ad-CMa45XXXXXX9ab.cpe.net.cable.rogers.com

    99.251.###.###

Are either or both of these guaranteed to continue to work, or can they arbitrarily change at any time?

 

(Note that the two XXXXXXs are identical.)

it Can Change, your getting a Dynamic WAN IP Address, but just because you were assigned the same one for a long time do not get comfortable with it, it can and has changed, what you need is a Dyn DNS. basically you need a static hostname that the IP address will change and re-direct to what ever your current IP becomes. DynDNS is the name of the service but theres lots of providers out there who offer such service, i had one back in the day, most modems support the config ,otherwise a quick script on your laptop or desktop will update the Hostname to your new IP.

This is what I do.

I used to use DYNDNS until they started charging 😞
I am using No-ip.   Its basic service is free, but if your IP doesnt change within a month and isnt updated to something new, it will notify you that it will be removed unless renewed... I get an email, do the quick renewal.

I have a small webserver running at home.  I have a registered domain, but I point that do the dynamic services address.  Then just update it.
