We have several remote sites in our company. I am considering changing static IP of each of those sites to Dynamic IPs. This of course will create a problem that we will not know IP address at any given point in time.
The workaround I am thinking of is for each of those remote sites to post their IP address every hour to our server. My questions are:
1. Is there a DOS-based or Windows-based utility through which a system can find out its public IP address (ipconfig only gives you the local IP) ?
2. Is there an existing web service that does that? There are services like no-ip.com but the problem with those is that they substitute your IP address with a string alias, e.g, myname.no-ip.com which won't work for us. We do need to get updated IPs, not aliases.
