You need to do a little more study on IPv6. The block FE80::/10 is for link-local unicast addresses. Read up on the IPv6 address space. You need to know that as you would know that 127/8 is the loopback address space in IPv4 and that 10./8 is one of the RFC1918 addresses. Now go read man ping6 and you will see how you can choose the source address and then you won't have to go round deleting link-locals every time you set up a host. I'm not going to type up the entire story. You'll learn more if you get yourself some resources. If you want hardcopy try "Running IPv6" by van Beijnum. Besides that my hands are not up to punching out long stories....... ;) Oh and please don't CC me. I AM on the list and I cannot read an email with each eye ;)) R/ *** NOTE *** Please DO NOT CC me.
