[SVCB DNS resource records](https://datatracker.ietf.org/doc/draft-ietf-dnsop-svcb-https/) (<abbr>RRs</abbr>) 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 <abbr>RRs</abbr>; Encrypted Client Hello and HTTP/3 are the main use-cases today.

To give <abbr>IPNS</abbr>-accessible services familiar names, I think SVCB is a better long-term solution than [DNSLink](https://www.dnslink.io/).

A related issue for the InterPlanetary Name System is [Issue 144 for the <abbr>IPFS</abbr> web browsers integration group](https://github.com/ipfs/in-web-browsers/issues/144); it discusses the viability of using `Alt-Svc` for this.
