Comment 42 for bug 121467

My code-reading skills are modest, so I'll ask rather than risk an invalid bug.

I was playing with some ad hoc testing of this function and I found that something like: www.host\.com fails with "hostname not found" error page.

I *think* it's because this function is used like this:

http://mxr.mozilla.org/seamonkey/source/netwerk/dns/src/nsHostResolver.cpp

417 // ensure that we are working with a valid hostname before proceeding. see
418 // bug 304904 for details.
419 if (!net_IsValidHostName(nsDependentCString(host)))
420 return NS_ERROR_UNKNOWN_HOST;

Should we have a different error conditions for illegal/invalid hostnames?
