Hello, I've been using this tool for several days and I'm loving it so far!
However, there's one minor issue: the tool does not recognize query types in lowercase (a instead of A, txt instead of TXT, mx instead of MX, etc...). I'm not familiar with C# per se, but I think this can be fixed by converting all query types to uppercase.
It would be better if dug behaved like dig, which is parsing query types when they're specified in place of the "verbs" i.e. dug mx example.com, since dug by default run with the verb "run".
Thank you for creating this tool!
