Usage guidelines
Different prefix pools cannot overlap.
You cannot modify an existing prefix pool. To change the prefix pool settings, you must delete the
prefix pool first.
Removing a prefix pool clears all prefix bindings from the prefix pool.

42. Prefix pool 1 contains 1024 prefixes from 2001:0410::/42 to 2001:0410:FFC0::/42.
