Static IP Problem

Question

I am trying to setup a CCTV DVR for off site viewing.The connection is via a home ISP so static IP is not offered.I am familiar with using DynDns to set up as a hostname via my netgear router,however the monitoring software does not support connection via host name,just IP.Any ideas on how I could achieve this? Is there a service to allow the hostname to convert to IP?

Any help would be much appreciated.

No. The only way to get a static IP is through your ISP.

"Is there a service to allow the hostname to convert to IP?"

Sure, there is, it is simply a recursive DNS lookup. This is nslookup on Windows and dig or host on other platforms. It's easy to write a small script to get the IP address for your DynDNS hostname. Alternatively, you can just query the output of http://checkip.dyndns.org/ via a script utilizing wget or cURL.

An example for a Windows .cmd or .bat script extract:

for /f "tokens=2 skip=4" %%i in ('2^>nul nslookup http://yourhost.dyndns.org.') do set myip=%%i

(Replace yourhost.dyndns.org. with your full DynDNS hostname, plus trailing dot.)
The environment variable myip will then contain your public IP address currently associated with your DynDNS hostname.
