[Pdns-users] IPv4 shared address space (100.64.0.0/10) Reverse Zone

[Giovanni Vecchi]

Hi Brian,

thanks for your reply.
At the moment I created every /16 reverse zone on my auth server and added
an entry for each of them on my recursor.
My doubt was only to avoid to miss a "smart way" of doing things.

Thanks
