I would like to build a local network consisting of several computers each of which is running a web server. These web-servers should communicate with each other. But the problem is that IP addresses could be different each time I start the network. So, every server does not know how to find another server.
I know that, in similar situation, people used Java in combination with zeroconf. Zeroconf finds all computers present in the network automatically and gives this information, in same way, to Java. Can I do something similar in PHP?
