Edit Question
Title
Body
The UUID specification defines 4 predefined namespaces which it describes as "potentially interesting" - meaning among other things, "if other people have generated UUIDs in this namespace you can verify them": 6ba7b810-9dad-11d1-80b4-00c04fd430c8 for DNS 6ba7b811-9dad-11d1-80b4-00c04fd430c8 for URL 6ba7b812-9dad-11d1-80b4-00c04fd430c8 for ISO OID 6ba7b814-9dad-11d1-80b4-00c04fd430c8 for X.500 DN Where did these come from? Specifically; If I'm generating my own namespace UUID do I need to avoid anything in particular? I'm aware how big the UUID space is, but does this have any implication on collisions? Why have they chosen the 4th octet to increase as a kind of UUID 'version number'? Do my questions imply that I'm missing something fundamental about UUIDs?
