unable to access sequelize.org with ipv4

[shuidian]

Hello, it seems that sequelize.org is deployed on an ipv6 address, which may prevent users who do not support ipv6 from accessing it. Could you consider deploying sequelize.org on an ipv4 address?

We can take a look at it, but IPv6 should be supported on all modern devices. What users are not able to access IPv6 addresses?

Also, can you share how you checked that it's deployed on an IPv6 address. When I do a DNS lookup I only see Cloudflare's IPv4 addresses
