Ranges	2a01:07c8::-2a01:07c8:ffff:ffff:ffff:ffff:ffff:ffff	149.210.128.0-149.210.255.255
Dual addresses	2a01:7c8:aab0:26e:5054:ff:1.2.3.4

Options:

ipv4_ranges: boolean: accept IPv4 ranges, e.g. 10.0.0.0-10.255.255.255
ipv6_ranges: boolean: accept IPv6 ranges, e.g. 2001:0db8::-2001:0db8:ffff::
ipv4_cidr: boolean: accept IPv4 CIDR suffixes, e.g. 10.0.0.0/8
ipv6_cidr: boolean: accept IPv6 CIDR suffixes, e.g. 2001:db8::/32
strict: boolean: strict mode

All options above default to true.

Strict mode

If strict mode is enabled, only one value (address, range or CIDR) will be parsed; everything else will be marked as erroneous. Example with an IP range: If strict mode is disabled, codemirror-mode-ipaddr parses and highlights all IP addresses in the text editor:
