+Verify an IPv6 address.
+
+Checks whether given argument is a preexisting luci.ip.cidr IPv6 address
+instance or a string literal convertible to an IPv6 address and returns a
+plain Lua string containing the canonical representation of the address.
+
+If the argument is not a valid address, returns nothing. This function is
+intended to aid in safely verifying address literals without having to deal
+with exceptions.

+
+<h3>Parameters</h3>

+
+ <li>
+ address: String containing a valid IPv6 address or existing
+luci.ip.cidr IPv6 instance.

+Verify an ethernet MAC address.
+
+Checks whether given argument is a preexisting luci.ip.cidr MAC address
+instance or a string literal convertible to an ethernet MAC and returns a
+plain Lua string containing the canonical representation of the address.
+
+If the argument is not a valid address, returns nothing. This function is

+
+<h3>Parameters</h3>

+
+ <li>
+ address: String containing a valid MAC address or existing luci.ip.cidr
+MAC address instance.

+<h3>Usage:</h3>
+<pre>mac = luci.ip.checkmac(luci.ip.new("00-11-22-cc-dd-ee")) -- "00:11:22:CC:DD:EE"
+mac = luci.ip.checkmac("00:11:22:cc:dd:ee") -- "00:11:22:CC:DD:EE"
