SYNOPSIS

use Net::DRI::Data::Hosts;
my $dh=Net::DRI::Data::Hosts->new();
$dh->add('ns.example.foo',['1.2.3.4','1.2.3.5']);
$dh->add('ns2.example.foo',['10.1.1.1']); ## Third element can be an array ref of IPv6 addresses
## ->add() returns the object itself, and thus can be chained
## Number of nameservers
print $dh->count(); ## Gives 2
## List of names, either all without arguments, or the amount given by the argument
my @a=$dh->get_names(2); ## Gives ('ns.example.foo','ns2.example.foo')
## Details for the nth nameserver (the list starts at 1 !)
my @d=$dh->get_details(2); ## Gives ('ns2.example.foo',['10.1.1.1'])
## Details by name is possible also
my @d=$dh->get_details('ns2.example.foo');

DESCRIPTION

Order of nameservers is preserved. Order of IP addresses is preserved, but no duplicate IP is allowed.

If you try to add a nameserver that is already in the list, the IP addresses provided will be added to the existing IP addresses (without duplicates)

Hostnames are verified before being used with Net::DRI::Util::is_hostname().

IP addresses are verified with Net::DRI::Util::is_ipv4() and Net::DRI::Util::is_ipv6().

METHODS

new(...)

creates a new instance ; if parameters are given, add() is called with them all at once

new_set(...)

creates a new instance ; if parameters are given, add() is called once for each parameter

clear()

clears the current list of nameservers

set(...)

clears the current list of nameservers, and call add() once for each parameter passed

add(name,[ipv4],[ipv6])

adds a new nameserver with the given name and lists of IPv4 and IPv6 addresses

name()

name of this object (for example for registries having the notion of host groups) ; this has nothing to do with the name(s) of the nameservers inside this object

loid()

local id of this object

get_names(limit)

returns a list of nameservers' names included in this object ; if limit is provided we return only the number of names asked

count()

returns the number of nameservers currently stored in this object

is_empty()

returns 0 if this object has nameservers, 1 otherwise

get_details(pos_or_name)

given an integer (position in the list, we start to count at 1) or a name, we return all details as a 3 element array in list context or only the first element (the name) in scalar context for the nameserver stored at the given position or with the given name ; returns undef if nothing found at the position/with the name given.
