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.

NAME
ypinit - set up NIS client SYNOPSIS
/usr/sbin/ypinit [-c] [-m] [-s master_server] DESCRIPTION
ypinit can be used to set up an NIS client system. You must be the superuser to run this command. This script need not be used at all if ypbind(1M) is started with the -broadcast option (it is invoked with this option from the svc:/network/nis/client:default service). Normally, ypinit is run only once after installing the system. It may be run whenever a new NIS server is added to the network or an exist- ing one is decommissioned. ypinit prompts for a list of NIS servers to bind the client to; this list should be ordered from the closest to the furthest server. It is recommended that you list each of these NIS servers by name and numeric IP address in /etc/hosts. Though the practice is not recommended, NIS allows you to list servers by numeric address only, bypassing /etc/hosts. In such a configuration, ypwhich(1) returns a numeric address instead of a name. ypinit stores the list of servers to which a client can bind in the file /var/yp/binding/domain/ypservers. This file is used by ypbind when run without the -broadcast option. OPTIONS
-c Set up a ypclient system. -m Build a master ypserver data base. -s master_server Slave data base. master_server must be the same master configured in the YP maps and returned by the ypwhich -m command. FILES
/etc/hosts File in which it is recommended that NIS servers be listed. /var/yp/binding/domain/ypservers Lists the servers to which the NIS client is allowed to bind. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWnisu | +-----------------------------+-----------------------------+ SEE ALSO
svcs(1), ypwhich(1), svcadm(1M), ypbind(1M), sysinfo(2), hosts(4), attributes(5), smf(5) NOTES
The NIS client service is managed by the service management facility, smf(5), under the service identifier: svc:/network/nis/client:default Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The ser- vice's status can be queried using the svcs(1) command. BUGS
ypinit sets up the list of NIS servers only for the current domain on the system when it is run, that is, the domain returned by the SI_SRPC_DOMAIN command to sysinfo(2). Care should be taken to ensure that this is the same as the desired domain for NIS client processes. SunOS 5.11 20 Dec 2007 ypinit(1M)
