This is a feature request similar to Central whitelisting of IP addresses on Invantive Cloud.
Allow defining allowed IP addresses by using wildcards and ranges.
For example:
::ffff:20.38.84.10-::ffff:20.38.84.20
will allow all IP addresses in the defined range.::ffff:20.38.84.*
will allow all IP addresses in the range ::ffff:20.38.84.0-::ffff:20.38.84.255.
