You're thinking in decimal. It's hex, and should go: fec0::0/126: 0-3 (0 reserved) fec0::4/126: 4-7 (4 reserved) fec0::8/126: 8-b (8 reserved) fec0::c/126: c-f (c reserved) And, to keep going... fec0::10/126 fec0::14/126 <--- (your example) fec0::18/126 fec0::1c/126 So yes, fec0::14/126 is actually the first address. - Mark -- Mark Kamichoff [EMAIL PROTECTED] http://prolixium.com/ Rensselaer Polytechnic Institute, Class of 2004
