Domain Name Check
A DNS database is like a phone book of host names.
All these databases are
linked so that when you are trying to get resolution, the DNS server that tries to
get resolution for you might get directed from one DNS server to another until
you either get resolution or you find out you can�t get resolution.
DNS, Domains, and Zones
Domains starting at a top level (i.e., near the root) are particularly
important for DNS operation. These domains are generally called Top Level Domains (TLDs),
and TLDs are often referred to by specific names.
The entire name space is called the root
domain, and some common first-level domains are called generic top level domains or gTLDs.
Examples of gTLDs are the com, net, and org domains. At the first level, there are also percountry
domain names, which are called country code top level domains (or ccTLDs).
There is
no technical difference between gTLDs and ccTLDs in terms of the DNS protocol; the difference
is in who manages the corresponding name space.

Reverse IP Lookup - DNS Test
DNS
Domain Name System (DNS) is the Internet�s mechanism for linking all the host
names and IP addresses on the Internet.
In other words, DNS is a distributed and
linked system of resolving names to IP addresses.
The DNS system is similar to
an environment in which all telephone information operators are linked together
so that your request can get passed to the appropriate operator.
All the URLs that you need to get resolution
for on the Internet are in a DNS
database somewhere. A DNS database
administrator has entered the name and IP
address into the database.
When you use a browser and request Who Is for
www.
find-ip-address.org,
www refers to a service,
and find-ip-address.org to the host name.
The .org refers to the
portion of the domain space where this host
is found. A URL is a combination of
the service, host name,
and domain where the host can be found.
Reverse DNS Check
Reverse DNS lookup identify host or hostnames that belong to given ip address.
If you want to find out IP address from domain then you need to enter domain
without http:// prefix. Otherwise it will not works.
Reverse DNS - Reverse Lookup
Second Reverse DNS lookup form use reverse IN-ADDR entry to find out
decimal numbers seperated with dots into in-addr.arpa domain.
For example find-ip-address.org resolve to ip address 208.76.80.74
but reserve DNS using IN-ADDR entry for Ip 208.76.80.74 resolve to 74.80.76.208.in-addr.arpa domain and it
point to our hosting server ambria.tchmachines.com.
