Hi keith
I will use the cisco community to answer your question.
dynamic dns are now going to charge for the dynamic dns resolution. So an alternative is to grab one free Dynamic DNS host account at www.noip.com
Here is the cli that has to be incorporated into the startup script and then tftp'd to the ISR881W router (reason, cannot paste some of the characters).
The debug on my router, as shown below, indicates that the update may have worked. My free account at noip.com however does not indicate that a update occured. This may not be an error.
regards Dave
ip ddns update method no-ip

ip dhcp-client update dns
interface FastEthernet4
description $WAN$
ip ddns update hostname myname.no-ip.biz
ip ddns update no-ip
ip address dhcp
ip nat outside
ip virtual-reassembly in
duplex auto
speed auto
end
Then I shut down the wan interface and did a no shut on the wan interface . DDNS updated so the debug and interaction with noip.com showed.
