[Exim4U] What certificate filename should I choose for MY_IP var in MULTI_IP = YES setup in case of IPv6?

Hi List! Could somebody please clarify which filename I should choose for certificates in MULTI_IP = YES setup in case of IPv6? ⇒ /etc/pki/tls/exim_tls/exim.MY_IP.key What’s $MY_IP in the case of this example: 1) FE80:0000:0000:0000:0202:B3FF:FE1E:8329 2) FE80::0202:B3FF:FE1E:8329 3) FE80::202:B3FF:FE1E:8329 Is it always 1) because computer do not short it, EVER? /etc/pki/tls/exim_tls/exim.FE80:0000:0000:0000:0202:B3FF:FE1E:8329.key ?
