As the domain name is "openbased.org", and with "based" being Internet slang, I don't think your correction applies. The name describes a based canvas built on IPv6, hence IPv6 Based Canvas.
The English language is rather particular when it comes to the order of adjectives, but according to https://dictionary.cambridge.org/grammar/british-grammar/adj..., "opinion" comes first, and "based" is very much an opinion. I suppose that means the grammatically correct name would be "based IPv6 canvas" if you're being pedantic.
