A number of these prefixes were used in early documentation
and as such were widely deployed by early adopters of IP.
In the "bad old days" a large number of sites stood up IP
networks in isolation, only interconecting -after- inital
rollout was done. Consider it as an early empirical trials
with RFC 1918 space :)
Based on the confusion, 192.0.2.0/24 was earmarked for
use in documentation... :)
I know of no good reason why Juniper continues to flag these
legacy blocks.
