By comparison, `getByName` will try to parse the given name as an IP literal, and if it can't parse it as an IP literal, pass it to the resolver. The new method will never invoke the resolver and throw in that case. I find the name `ofLiteral` to be closer to what the method does than it would be if we provided it as an override to e.g. `getByAddress`, but naming can be discussed.

Well, the getByAddress methods are already providing a variation on the proposed functionality, and as such it makes sense from an OO perspective (polymorphism) to provide an overloaded method to perform the proposed functionality.  getByAddress is doing "what is says on the tin" ... ofLiteral conveys no semantics  and is more cryptic or nuanced
