I don't know where the \142 came from here.  But as a result, it thought 
you were trying to look up the name "\142 at serverIP", not 
"mydomain.com.co".  I'm not sure why it reported "NOERROR", it should 
have reported "NXDOMAIN".

This is a normal result if you don't have an A record for the name 
"mydomain.com.co".  If you've defined subdomains like 
"www.mydomain.com.co", are you able to resolve them?
