You can now create HTTPS DNS records in Vercel DNS.

The new HTTPS DNS record type, also known as SVCB or Service Binding record, has recently been published as RFC 9460.

This record type is designed for the HTTP protocol to improve client performance and privacy in establishing secure connections. The record can include additional information about the target server, such as supported ALPN protocols (e.g., HTTP/2, HTTP/3, etc), which can eliminate the need for protocol negotiation/upgrade between client and server to minimize the number of round trips.

Since the HTTPS record type is still a new standard, not all HTTP clients can support it. Learn more in our documentation.
