Virtualmin => Addresses and Networking => Dynamic IP Update <<< needs some modernization/updating?

Yes, maybe, if it's good for Virtualmin and the users now and in the future.

I see it's complicated. Like my router only allows No-IP and DYN to connect to it. How many routers are their that restrict options, and so on. throws hands in air

For the record, I'm having the worst experience trying the ChangeIP.com service. It seems like the Microshaft business model; a pretty marketing wrapper on an old rusty garbage can. Support responses don't pass the Turing Test. My transferred domain doesn't work yet:
e,g,
This site can’t be reached
MyExample.com’s server IP address could not be found.
Try:
Checking the connection
Checking the proxy, firewall, and DNS configuration
ERR_NAME_NOT_RESOLVED
and it's been 7 days since I completely and successfully transferred it from domains.google.com. Even Google had all my subdomains working correctly, they just fouled up the main domain. ChangeIP has nothing working right.

Also, their interface is confusing and throws error messages that don't help, but that's not in their control because it's made by "WHM Complete Solution" http://www.whmcs.com/ so it's not worth complaining to ChangeIP about their interface.

While on the No-IP pages I see this gem about routers:

What If No-IP Isn't an Integrated Solution in My Router or Device?
-
It’s not a problem if No-IP isn’t an integrated solution in your device, but you should take a few seconds to write an email or tweet to your device manufacturer and ask them to add No-IP as a Dynamic DNS provider. It will make your life easier, we swear. In the mean time… If No-IP is not an integrated solution in your router or device, we offer an easy and free solution. Simply download our Dynamic Update Client, which is available for Windows, Mac, and Linux. Install the software at the location where you would like your IP address to be updated with your hostname. The Dynamic Update Client must be running at all times in order to keep your hostname updated with the current IP address.

So people could pressure the router Mfg. to do a firmware change supporting other services?! Cool. I wonder how many reliable DDSN providers could take advantage of this?

Also, couldn't the coders at Webmin fork some program that updates DDNS service providers in a way that it runs like a daemon in Webmin updating Virtualmin itself and the BIND records?

Also, if a user had their domains listed on a variety of services, they can only update one service with their router, the rest can get the update by a piece of software running in the background on their system.

As an add-on to #7 above, it seems that any dynamic IP updater program you write should be virtual server dependent. This would allow individual API selection for the unique needs fo that domain. Perhaps during spin-up of a virtual server that's dynamic IP dependant, the user would select the DNS provider and enter their username and password to manage that domain. Then via API connections, your software would log in and update the IP as the Virtualmin daemon software discovered the change.

This is more of a "Note To Self" comment than an update or a question. Today I switched ISP's because Verizon doubled my monthly bill for no reason, so my IP address was changed. I've been getting better at changing things mostly because I'm using Virtualmin's tools instead of doing things the hard way. Last time I went into the BIND DNS Server settings and changed all the IP's, the time before I manually edited the text file using the file browser. I was just ignorant to the better ways. Today I just opened each virtual domain and did the Virtualmin => selected v-server => Server Configuration => Change IP Address, and now I see the title of the thread hinted at what I should have done in the first place.

Virtualmin => Addresses and Networking => Change IP Update

I was a little put off by it because the interface makes me fear I could do something wrong and F.U.B.A.R. my server. My courage is up though so I'll try it next time. I'm assuming I should have changed the radio button for Address type to change to "External address used in DNS records" and fill in IPv4 address of servers to update with the last IP address and fill in New IPv4 address with the current IP address.

Just recently I posted to the forum... Dynamic IP update the zones

So in my reply, I wrote about an Ubuntu program that I found out about recently called ddclient. It's obvious that there were a lot of ways to go about using it but I only cared about connecting to Google. I see its useful enough though that you might think about a new module suggestion (a module that doesn't exist yet but would convert Virtualmin servers into entries for the ddclient config file), for anybody that chooses the Dynamic IP updating. Oddly, with this type of program, I don't need to run a script. To work-around that I made a dummy script that will do nothing...

Since the client program is just Linux stuff, I'd bet every supported OS has it already.

It seems that there should be another option that would allow the user to activate nothing. I'm not sure when the next dynamic update will happen, but hopefully, I will get the eMail that it was triggered. I have that ddclient checking every 7 minutes and Virtualmin looking every 5. The ddclient is pretty cool and if you don't set it right, Google won't point at your IP. Once you do what Google tells you to, your IP is 0.0.0.0 until they hear from ddclient what your IP is. This is what mine looks like...

... and so on.

I'm not trying to think of my personal needs here though. I got my solution already. I'm wondering if it would be an improvement on the whole Virtualmin product if us users could select a, "No Virtualmin to DNS Service Provider action necessary", option (or an "I'm running the ddclient software" option), and... ...because this great solution was obscure to me, make it part of the Virtualmin ecosystem.

I can envision a great module that manages the ddclient software. Users could pick the service they use from the list of supported service providers. (Here's a short-list of supported Dynamic DNS provider's.) Then the appropriate text-boxes for that provider would appear for the user to fill in, maybe with a link to the Dynamic DNS provider's page if it exists like the Google one I found. The module would then write that entry into the /etc/ddclient.conf file.

I don't know how easy it is to have the OS detect that it's getting it's IP's dynamically, but if it could, it seems that this software should be suggested to the user during the install process, or be set-up like other modules that are just part of the base Virtualmin package waiting to be used.

@agnostic That's freaking great!
