Openssl s_client verify_ip usage on ip wildcard matching

Hi

Does verify_ip supports leftmost wildcard?
I know that hostname does for SAN and CN. But ip address seems to only
support exact match including the port?
Is that observation correct?
What does it take for  verify_ip to support leftmost wildcard matching just
like DNS hostname?

Thanks
