SBS 2011 Dynamic IP GoDaddy (forced update)

I am running SBS 2011 using a dynamic IP internet connection. I have an account at GoDaddy for my domain.

Is there a way to force SBS 2011 to update the IP address at GoDaddy without waiting the normal refresh time?

I don´t want to run the internet address wizard for doing that because it changes my SSL certificates to self issued ones.

When doing tests and configs that require my internet modem to boot it is common to have a different IP every time. I want to force an IP update as soon as the connection is up to continue with my tests/configs.

Thank you in advance!

1. get a static ip from your isp which probably requires a business vs residential service account.
2. pay a company like dyndns  and point your godaddy nameserver address's to dyndns.

use a very short TTL is the only way

Davids completely right here.

You're best option (by far) is to get your ISP to provide you with a static address.  This may cost you a little more money on your broadband package but its needed.

Dynamic DNS is only a bodge in this instance.

I agree with you the static IP is the best option but it is not available for this installation.

Is there a way to force SBS 2011 to update the IP address immediately at GoDaddy?
Amazon Web Services

Are you thinking about creating an Amazon Web Services account for your business? Not sure where to start? In this course you’ll get an overview of the history of AWS and take a tour of their user interface.

Not to my knowledge.
You would need to use dynamic DNS and then perhaps use CNAMES pointed to the dynamic DNS address.

Then dynamic DNS agent will update and no DNS records would need to be changed.

Test before deploying in production.

Here I use a cable modem (lan port dmz)->(wan port) tp-link router -> switches -> computers. And I never have to reset my cable modem.  I have a dynamic account at my ISP and a changing public IP is a real pain.. I have many accounts set up elsewhere i.e. Azure/Digicert that are locked to my public ip address .. so my suggestion is to add a router after your internet connection and before your LAN

Dear David,

Thank you for your comment. Your suggestion is similar to what I actually have. I have 2x Cisco DPC 3925 connected to one RV-320 load balancing router. Different ISP on each cable modem but both of then with dynamic IP.

I am testing configurations that need to reset the cable modem to apply and sometimes I must reset the router also.

That's why I would like to find a way to tell SBS 2011 to update the GoDaddy registration everytime I want and immediately. The update takes sometime to propagate but adding the update time I takes forever!

I don't use godaddy other than a registrar same with 1AND1 I use cloudflare for my name server
David Johnson, CD, MVPOwnerCommented:
then you need to add another router downstream of each cable modem so that the cable modems don't get reset

I appreciate all the comments and suggestions but no solution was presented.

I don´t know how to force SBS 2011 to update GoDaddy immediately upon request. This is the point I would like to have addressed. Is there a way to restart a service for doing so? Is there a command line I could use?

I agree with the experts comments that the setup is not the ideal but I can´t change it by now. I must put what I have to work.

What about using open dns?  I seem to remember the service gives you a static ip that maps to your dynamic ip.  It continually checks if your dynamic ip changes and if it does updates the service so it is like having a static ip.
David Johnson, CD, MVPOwnerCommented:
using a dynamic dns provider has already been suggested and opendns doesn't have that feature.. you are trying to transform a mac truck into a sports car. by being provided with a dynamic public ip instead of paying for a static ip you are resigned to live with the consequences. All you can do is automate the changing of your public ip address in your registrars dns records and having very short TTL's on your dns records.. That is the limit of what you can do. There is nothing that has to be changed within SBS, no service that can be restarted to speed things up.. Once the record is changed you still have to wait for the update to propogate
