>Description:
You've probably heard about the site deviantart.com. This site has a user account with "zi-" name and complete address is http://zi-.deviantart.com . When I try resolves this address using nslookup (dig or host) is not a problem but when trying to open this address from any browser or execute the command ping for this host, I get the error "ping: cannot resolve zi-.deviantart.com: Unknown server error"

Nevertheless, if the address register in the /etc/hosts "199.15.160.42 zi-.deviantart.com" problem is solved.

I think that the system does not properly handle dns names with a minus in front of the dot, since if the minus is between letters is not a problem.

p.s. The problem was not detected in OS windows >_<
>How-To-Repeat:
make "ping zi-.deviantart.com" and get the error message
>Fix:
Is't very good idea but as temporally solution write string in the /etc/hosts file for each problematic address :(
