From what I have read, I have come to understand that all WordPress plugins,(including premium ones) should be GPL licensed. If this is the case, can the installation be limited to a single domain? As far as I understand, GPL allows you to reuse the code. Doesn't it? I'm asking this because I have seen some premium plugins have single site/multi site licenses. Please correct me if this question is wrong.

The ones I've seen just restrict their support contracts to single sites etc. Some times it's termed "licensing" but it'd be better to call it support contracts. It's probably related to, and originating from, the language disclaiming warrenty unless blah blah blah... part of the licensing. – WraithKenny Mar 27 '12 at 23:52

GPL prohibits restricting the code in any way. You can restrict the support or non GPL parts of the plugin (images/css) to a single domain but you can't restrict the GPL code to a single domain.
