-      simply ignore them or only use the first one.
-      The <code>family</code> attribute can be set to
-      either <code>ipv4</code> or <code>ipv6</code>, and the
-      <code>address</code> attribute contains the IP address. The
-      optional <code>prefix</code> is the number of 1 bits in the
-      netmask, and will be automatically set if not specified - for
-      IPv4 the default prefix is determined according to the network
-      "class" (A, B, or C - see RFC870), and for IPv6 the default
-      prefix is 64. The optional <code>peer</code> attribute holds the
-      IP address of the other end of a point-to-point network
-      device <span class="since">(since 2.0.0)</span>.
