The template can contain four tokens: "%(a)d", "%(b)d", "%(c)d", and "%(d)d", representing the four bytes of the IPv4 address, respectively, in decimal notation. Moreover you can use any standard printf format specification like %(a)02x to get the first byte as two hexadecimal digits. Usual choices for mapping 198.51.100.0/24 to 2001:0DB8:1:1::/64 would be "2001:db8:1:1:%(d)d::" and "2001:db8:1:1:%(d)02x00::".', blank=True, verbose_name='ipv6 template', validators=[firewall.fields.val_ipv6_template]),
