According to the main page of Sedo they have 124986 .eu domains on offer at present.
If you combine the numbers from Sedo with those you get from a quick search on say Afternic then the number climbs to close to 200 000 domains…
If you then add the domains that don’t even have dns or anything else and have simply been “dumped” in a corner, how many active .eu domains are you left with?
