[Commentor] LC-401 Zev Blut [Working Group decision] No specific values have been defined for lengths of URLs because it was felt that specifying precise value might in practice prove too restrictive This BP should be interpreted as meaning if you have the choice between link http://example.com as the access point for your site you should choose the shorter one, which we have tried to clarify through additional examples.

What does the group consider a proper range for short URLs?
