Is it dashes or underscores or both in machine names that can cause problems with DNS?

As per RFC 952 and 1123, the following are acceptable:
A through Z (uppercase letters A through Z)
a through z (lowercase letters a through z)
0 through 9 (the numbers zero through nine)
. (dot or period)
- (hyphen or dash)

The following characters are specifically excluded:
_ (underscore)
/ (slash)

Just for your info, Microsoft's implementation of DNS allows both dashes and underscores in machine names, but I believe other "flavors" of DNS do not. Hope this helps!
