In this post, the author writes about Dynamic DNS as necessary to OpenVPN. But I read some about ddns and CS an cannot tell whether this step is necessary for me. I quote it, below:
What I've read at the Forum does not inform me of what I need to do here. Currently there are approximately 33,337 providers of the DDNS service.Setup DDNS
First, we’ll need to setup dynamic DNS (DDNS). We’ll be running a server out of our house, and since our ISP regularly changes our IP address, we’ll never know when the address changes. Instead, we can run a small program on OpenWrt that will reach out to a DDNS provider, tell them what our IP address currently is, and associate it to a DNS name. This way, when setting up our OpenVPN clients, we’ll use the DDNS name, not our IP.
If you don’t have one already, you’ll need a DDNS provider. I’ve been a Dyn customer since before all the drama about discontinuing their free accounts. Make sure you choose a provider that is supported by OpenWrt. Once you choose a provider, you’ll need to register a DNS name with them.
You’ll also need the following info about your account:
DDNS service name (as listed here, or in /usr/lib/ddns/services)
Password (some providers offer an updater key instead of exposing your password)
Interface you’ll be using to get DNS info (e.g., wan, wan6, lan, etc…)

I am running all Internet traffic through this router (and it's wifi) into a modem supplied from the ISP.
How can I tell if my ISP regularly changes my IP address? (Looking up the following keywords brings useless results: AT&T change IP address)
Does CS require DDNS if the router is the only way to access the Internet?
If "Yes" does CS sell, recommend or can you refer me to a service the CS developers know and prefer, or at least approve?
Know that I'm not a networking sophisticate, as nearly everyone else is at this Forum. I can cut & paste but that's about it. I don't want to waste your time in replying to this post of mine. Excellent technical explanations may help others, they are likely to further confuse me.
