I have a web server with a public IPv4 address. For this IPv4 address, I have a DNS A record for "domainA.com". Since more IPv4 addresses cost money at my hosting company, I am thinking about using a free IPv6 address to host another website on this server.
(I need a different IP because I want to use SSL Certificates. Apache is not able to distinguish between the domain names on a single IP, when the browser of the client don't use SNI, so there are certificate errors)
If I use a IPv6 DNS provider to map my domain "domainB.com" to the IPv6 address with an AAAA Record, are IPv4-only clients able to reach the Website? And if they are not able, is there any service or similar to make this possible?
