The % stuff is telling you which network interface it is associated with.  At 
the ping level, you can use things like xxxxxx%eth0 to tell it to use eth0 as 
compared to eth99.  It lets you use link-local IPv6 addresses, or something 
like that.

There is probably a way to turn it off.  I haven't looked.  That code is in 
libntp/socktoa.c.
