EDNS amber vs green on dnscheck tools site

[SkippyP]

When using my ISP’s DNS, the “EDNS” indicator at the bottom of the dnscheck tools site is amber. But when using Cloudflare, it’s green. Does anyone know what the different colors mean?

Thanks. So my ISP’s DNS doesn’t support UDP buffer sizes above 1200?
