It's a binary form. We need 40 bytes for global address. To save
site-local or link-local address, we need more space for scope
identifier. I believe the length of scope identifier is not defined
and system specific.
global address:
1234567890123456789012345678901234567890
NNNN:NNNN:NNNN:NNNN:NNNN:NNNN:NNNN:NNNN\n
scoped address:
1234567890123456789012345678901234567890
NNNN:NNNN:NNNN:NNNN:NNNN:NNNN:NNNN:NNNN%fxp0\n
There is one more consideration. `:' is conflict with X. I have no
particular idea to solve this problem. Enclosing IPv6 address with
`[' and `]' doesn't help without changing X side.
