NAME

Net::DRI::Data::Hosts - Handle ordered list of nameservers (name, IPv4 addresses, IPv6 addresses) for Net::DRI

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

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.
