There are also two shorthands for prefix patterns: <cf><m>address</m>/<m/len/+</cf> is a shorthand for
<cf><m>address</m>/<m/len/{<m/len/,<m/maxlen/}</cf> (where <cf><m>maxlen</m></c> is 32 for IPv4 and 128 for IPv6),
- that means prefix <cf><m>address</m>/<m/len/</cf> and all its subprefixes. <cf><m>address</m>/<m/len/-</cf>
- is a shorthand for <cf><m>address</m>/<m/len/{0,<m/len/}</cf>, that means prefix <cf><m>address</m>/<m/len/</cf>

For example, <cf>[ 1.0.0.0/8, 2.0.0.0/8+, 3.0.0.0/8-, 4.0.0.0/8{16,24} ]</cf> matches
