I'm currently using 000webhost.com to host my code. In the tracking server, I notice some samples using the format namespace.112.2o7.net. I'm currently using 112.2o7.net only. What is the difference?
Also, the URL for my site is in the format of mysite.000webhost.com. Would mysite.000webhost.112.2o7.net work as tracking server? I'm curious because I don't see anyone using subdomain on their tracking server.
2o7.net (and its subdomains) is where the visitor ID cookie is stored. using 112.2o7.net technically works, but you'll be sharing that cookie with everyone else who's using it.
If you have the capability to easily alter this value, I'd strongly recommend using 000webhost.sc.omtrdc.net. This is our regional data collection server, which increases performance. It also automatically routes to the proper data center.
