## dotted-to-ipaddr

Arguments: dotted &key errorp

If dotted is a string like "192.132.95.84" (or one of the extensions to this format), this function converts the string to an unsigned 32-bit IP address. If there are any invalid characters in the string then an error will be signaled unless the value of errorp keyword is `nil`, in which case `nil` is returned.

dotted-to-ipaddr supports IPv6 "colon hex" address notation, including the %scopeid extension. The scope id can be an interface number or interface name. dotted-to-ipaddr supports IPv4-mapped IPv6 address notation (::ffff:w.x.y.z).

### IPv6 colon hex notation examples:

    "2001:5c0:0:2::24"              ;; 6bone.net
    "fe80::209:5bff:fe8e:61c1"      ;; a link-local address
    "fe80::209:5bff:fe8e:61c1%eth0" ;; a link-local address with scope-id
    "fe80::209:5bff:fe8e:61c1%2"    ;; a link-local address with numeric scope-id
    "::"                            ;; unspecific/wildcard address
    "::1"                           ;; loopback
    "::ffff:192.168.0.1"            ;; IPv4-mapped IPv6 address
