Ah, I see! Caught by surprise! Don't special-case '#', but it's
easy to write a function to tell whether a word could potentially
be a valid hostname or IP address:
int ap_hostname_syntax(char *s)
{
for (; *s; s++) {
/* Allow : for IPv6. */
if (!isalnum(*s) && strchr("_-.:", *s) == NULL)
return 0;
}
return 1;
}
I suggest using that where a valid hostname or IP address is required.
