Is there a way to specify an IP address range in the Subject Alternative Name part of an SSL certificate?

Solution Verified - Updated -

Issue

The question is if there is somehow a chance to get an IP address range into the Subject Alternative Name? For example, through a syntax like this:

[...]
subjectAltName = @AltName[ AltName ]

IP.1=172.16.0.0-172.16.255.255
DNS.1=*.corp.tld
[...]
