@chicocanada  You need a Shaw business internet account to get a static ip.

Obtaining a "static" IP-address won't help. If Shaw moves your cable-modem into a different subnet, you'll get a new IP-address, whether or not your current IP-address is "static" or "dynamic".

I can ask to know the static IP ahead of time and look up the CIDR and whitelist it before I get switched over.

@chicocanada -- the difficult part is knowing "when" Shaw will make a change that will result in a different IP-address for your cable-modem, and you reconfiguring your setup before the change is made, e.g., continue to allow access from your current IP-address, and add access from the "future" IP-address.

Can you monitor: https://support.shaw.ca/t5/service-updates-outages/tkb-p/service-updates

to get some notice of future Shaw changes in your area?

@mdk @chicocanada  I wonder if a dynamic dns service might help?

@chicocanada -- my server is remote, as in remote to me (USA).

Tough problem, if the server in the USA is firewalled to accept connections only from one IP-address, and that IP-address is supplied by Shaw, and then Shaw changes the IP-address.

However, if you could schedule a repeated task on your server, you might have a solution.

If you know your current IP-address in Calgary, e.g.,

Address: 77.66.55.44

Name: S010161c9d7275f84.cg.shawcable.net

your host-name, namely: S010161c9d7275f84.cg.shawcable.net  will never change, until you change your cable-modem, even after Shaw changes the IP-address.

So, if the task on your server asks Shaw for the IP-address currently associated with that host-name, your server will get the current IP-address of your computer in Calgary, and your server can choose to accept connections only from that host-name.

In this case, the NOIP site probably is not helpful to you.
