My website only has an IPv4 address. With IPv6 being the future, is it possible that some users may not be able to reach the website if it does not have an IPv6 address? Also, does having an IPv4/IPv6 address increase SEO performance?

Lack of IPv6 support on your site will hurt some of your users.
您网站上缺少IPv6支持会损害您的部分用户。
According to stats published by Google 20-25% of users currently have IPv6. A large fraction of those users will need to go through some kind of NAT to reach IPv4-only services, which will make connectivity less reliable.
根据谷歌公布的统计数据,20-25%的用户目前拥有IPv6。这些用户中的很大一部分将需要通过某种NAT来达到仅支持IPv4的服务,这将使连接不太可靠。
The fraction of users without any IPv4 connectivity whatsoever is negligible. But for those users who have both IPv4 and IPv6 connectivity your site will be more reliable if you support both as well. Many clients now support RFC 6555 which will allow them to automatically fail over between IPv4 and IPv6.
没有任何IPv4连接的用户比例可以忽略不计。但对于同时具有IPv4和IPv6连接的用户,如果同时支持这两种用户,则您的站点将更可靠。许多客户端现在支持RFC 6555,这将允许它们在IPv4和IPv6之间自动进行故障转移。
Also keep in mind that if a network with both IPv4 and IPv6 support has a DHCP server outage the users on that network will still be able to reach mainstream sites, but if your site is IPv4-only they will not be able to reach your site. Thus they might conclude your site is down and not realize there is a problem on their network.
另请注意,如果同时支持IPv4和IPv6的网络有DHCP服务器中断,则该网络上的用户仍然可以访问主流网站,但如果您的网站仅限IPv4,则无法访问您的网站。因此,他们可能会认为您的网站已关闭,并且没有意识到他们的网络存在问题。
