I know that IP address 127.0.0.1 in IPv4 is specially reserved for loop back on a local host. I think there is something special about IP addresses in the range 10.0.0.0 through 10.255.255.255 in IPv4 as well (something about invisible local area network systems, I think). I am looking for a listing of special IP addresses and ranges for IPv4, and if possible IPv6. I am also curious if anyone has used IPv6 addresses with Speakup configured kernels. Any pointers or info will be much appreciated. Thanks, and have a _great_ day! -- Ralph. N6BNO.
