Operating Systems Linux Domain registrars & DNS servers Post 302959579 by cjcox on Wednesday 4th of November 2015 03:33:04 PM

Think of nameservers as something different (but not necessarily) from your domain.

It's the DNS that holds the zone data for your somedomain.com. To make that official as far as the Internet goes that's why they are asking where your records go... that is what nameservers house the records.

Anymore unless the company is sizable, I chose to use a world wide redundant DNS service (multiple DNS servers with redundance) to house records for a domain (e.g. DNSMadeEasy for example). But as I alluded to earlier you can certainly host your own DNS server(s) (they like for you to have more than one if possible).

When DNS queries are made, ulimately thigns work from the root server down to the tld's etc... and along those paths, your case .com knows who (what DNS servers) stands authoritative for somedomain.com.

With that said, you or anyone else can choose to point to a DNS that "says" it stands authoritative for records for whoever (somedomain.com, mil.gov, etc)... if if that is your DNS that your pointing to you'll get back whatever name to IP (etc) that you have defined there.

Hope that wasn't too confusing.

Maybe another example. The Whitepages is a phone book. I could print my own phone book and change anyone's phone number I want. But this doesn't work at large because chances are people are using the official whitepages and not my hacked up copy.

Net::DNS::RR::LP(3)					User Contributed Perl Documentation				       Net::DNS::RR::LP(3)

NAME
Net::DNS::RR::LP - DNS LP resource record SYNOPSIS
use Net::DNS; $rr = new Net::DNS::RR('name IN LP preference locator'); $rr = new Net::DNS::RR( name => 'example.com', type => 'LP', preference => 10, locator => 'locator.example.com' ); DESCRIPTION
Class for DNS Locator Pointer (LP) resource records. The LP DNS resource record (RR) is used to hold the name of a subnetwork for ILNP. The name is an FQDN which can then be used to look up L32 or L64 records. LP is, effectively, a Locator Pointer to L32 and/or L64 records. METHODS
The available methods are those inherited from the base class augmented by the type-specific methods defined in this package. Use of undocumented package features or direct access to internal data structures is discouraged and could result in program termination or other unpredictable behaviour. preference $preference = $rr->preference; A 16 bit unsigned integer in network byte order that indicates the relative preference for this LP record among other LP records associated with this owner name. Lower values are preferred over higher values. locator $locator = $rr->locator; The Locator field contains the DNS target name that is used to reference L32 and/or L64 records. COPYRIGHT
