I deploy cellular modems that currently have sims with static ip addresses. For various reasons, we may move to providing sims without static ips.
The cellular modem supports DDNS (bluetree modem). Is there any DDNS software that I can use so that I may tie each deployed modem to a sub domain of a domain I own?
Or is it better to just stick with a service and pay the fee?
We had a look at some available open source to provide a dynamic DNS service some time ago, and in the end decided to go with a commercial service, because none of the available solutions really convinced us, and we decided that keeping such a service running is not our core business. If you want to know, we went to Dyn.
