Well, 127.0.0.1 is ok for resolv.conf on the name server, very portable unless you want to see it from the outside. Any client app will use resolv.conf to find a name server, so that name server must be an ip or in /etc/hosts to give the ip.
The server side of having a domain is to have a parent list you as its child. Then, even if hosts point to other initial name servers, they get the answers from you.
DNS is a bit insecure, so it is nice to use it with dnssec, which in turn requires that you get a certificate trusted by someone trusted.
You can put some convenient lies in DNS, but I am not sure what sort of "control" you get. I once set up a DNS that said aol was the firewall, where there was a forwarding proxy to the real aol. Since all external DNS inquiry went through the firewall DNS server, it intercepted all such requests.
You do not need roots to get DNS going, you use your ISPs DNS as your roots, and they redirect you to the real ones so you do not have to know when they change.

Net::DNS::Mailbox - DNS mailbox representation
SYNOPSIS
use Net::DNS::Mailbox;
$mailbox = new Net::DNS::Mailbox('user@example.com');
$address = $mailbox->address;
DESCRIPTION
The Net::DNS::Mailbox module implements a subclass of DNS domain name objects representing the DNS coded form of RFC822 mailbox address.
METHODS
new
$mailbox = new Net::DNS::Mailbox('John.Doe@example.com');
$mailbox = new Net::DNS::Mailbox('John Doe <j.doe@example.com>');
Creates a mailbox object which represents the DNS domain encoded form of the mail address specified by the character string argument.
The argument string consists of printable characters from the 7-bit ASCII repertoire.
address
$address = $mailbox->address;
Returns a character string containing the RFC822 mailbox address corresponding to the encoded domain name representation described in
RFC1035 section 8.
DOMAIN NAME COMPRESSION AND CANONICALISATION
The Net::DNS::Mailbox1035 and Net::DNS::Mailbox2535 subclass packages implement RFC1035 domain name compression and RFC2535
canonicalisation.
