The primary purpose of SVCB records is to decrease the time and complexity of the client lookup by providing the origin IP address directly rather than forcing the client to fetch the A/AAAA or CNAME record in cases where resources are served over a load balancer framework or from multiple endpoints designed to be equally authoritative.
Example configuration and reference

example.com 3600 IN HTTPS 2 example.org alpn=”h2”
