Can I have Wildcard SSL for IP Address ?

For protecting multiple IP addresses, Wildcard SSL is not possible. One has to buy either Single Domain or Multi-Domain.

Say, you wish to secure, say an entire range of IP addresses from 192.168.52.1 to 192.168.51.255.

For this, is it possible to buy Wildcard SSL for 192.168.52.*?

Unfortunately, no. That’s not possible.

For securing this IP address range, either one can buy Single Domain for each IP or Multi-Domain Intranet SSL certificate with required IP address in SAN values.
