thank you for the responses ... and Matthew I think it is getting clearer now .... however you mention: > you > probably have installed a caching nameserver. i used the Bind Configuration tool; initially when it generates the DNS records files, the configuration is caching nameserver; however, when I imported my hosts file, it automatically also created addition zones which includes my domain - lab.mycompany.com. I checked my /etc/named.conf configuration against a sample configuration URL and compared a "caching" vs "standard DNS" and it seems like I have the standard DNS configured ... can someone pls confirm that the info I am following is correct?
