I don have a static IP address or domain name. Can I still use Pixory?
Yes! Pixory is intended for just such a scenario. You can easily acquire a free dynamic domain name for your personal server. An explanation of dynamic dns can be found at technopagan, which includes a list of providers at the bottom. A couple of good free dynamic dns providers: www.dyndns.org, www.dynu.com. Once you have a dynamic dns name for your machine, go to the advanced configuration page in Pixory and enter that dns name in the “wan hostname” field.
