71 <p> %i and %r also allow explicitly defining the separator; eg %.i
72 or %_r. '.', '-', and '_' are the only characters<br />
73 supported since DNS names may not contain most other
74 non-alphanumerics.</p>
75 <p>%blank% may be used to specifically prevent template expansion on
76 a segment of a block if desired; eg, if<br />
77 192.168.23.0/24 has "unused-%i.example.com" set, adding an A+PTR
78 template for 192.168.23.48/30 of<br />
79 "%blank%" will leave 192.168.23.48 through .51 without PTR records
80 unless specific entries exist for those IPs.<p>
