Hi, I'm newbie and my english is bad. I'm studying "DNS and BIND" but I haven't a pubblic IP. I would test what I'm studying, so I would use the computers of my LAN. CAn I do it? If I set a primary domain as localhost, can I set subdomains, second level domain, as pc1,localhost? And a computer can be the nameserver? Can I test mailserver also? Thank you!
