Using DDNS service to lock IP

royganan asked 2 years ago

Hello,
I have a DVR in my office which is connected to a modem/router with LAN cable. If I want to access the DVR from my home i need to have a static IP address for my office.
I tried to use a DDNS service to point me to the IP address in my office,but when the IP in my office is changing then the DDNS does not work.
Is there a way to solve this problem so that the DDNS will point to the correct IP even if it changes? I thought that the DDNS services where made for those who wants to avoid the need for a static IP.

thanks for your help

Thanks for your question royganan.

If you are intending to stream the DVR data over the internet to your home, it may not work very well depending on the level of service you have at your office. The speed you have for upload in the office will be the best available speed for download at your home. For example, if you have a 1.5up and 768down DSL connection in the office, the best you will have available for the data stream will be about 600K due to overhead.

The Dynamic DNS services are fairly good but there is always going to be a delay between when the IP changes and the DDNS service updates. Different services will vary on how fast they update. The IP shouldn't change more then once every 8-12 hours though.

If you are using CenturyLink at the office you should be able to get a Static IP for a one time fee and no additional monthly charge. If you use CenturyLink with a dynamic IP address, they us a pool of 10 or so addresses that your connection rotates through. If they do that sequentially you might be able to use that information to improve the reconnect speed through your DDNS service.
