DNSLink and SVCB DNS resource records 2022-10-25T14:50:18-07:00

SVCB DNS resource records (RRs) were introduced somewhat recently. They inform user-agents that a given resource exists at another endpoint, possibly with extra parameters. Functionality closely mirrors the Alt-Svc standard. A profile of SVCB exists in HTTPS RRs; Encrypted Client Hello and HTTP/3 are the main use-cases today.

To give IPNS-accessible services familiar names, I think SVCB is a better long-term solution than DNSLink.

A related issue for the InterPlanetary Name System is Issue 144 for the IPFS web browsers integration group; it discusses the viability of using Alt-Svc for this.
