Is there any software to find out the ip-address of the Domain name without using the site?

What is bkhost Name Server?
Each website is identified by an IP address. When you want to access any website, you will type IP into the browser bar. Because IP is extremely confusing and difficult to remember, "domain names" were born to help us.

However, the domain name cannot replace the IP address, it only serves as an intermediary to lead to the IP address you want to access. Therefore, a server is needed to perform the process of translating domain names into IP addresses, and that server is called the Name Server (or DNS Server) - the domain name server.

What are the characteristics of bkhost Name Server?
The Nameserver maintains a directory of domain names that match certain IP addresses (computers). Information from all names on the Internet is gathered in a registration center.

Therefore, the Name Server can allow users to access the website with a familiar domain name, instead of having to remember a complex series of IP address numbers.

Nameserves on-line can access information at registration centers up to 8 hours after registration of international domain names .COM and .NET time can be updated up to 48 hours for all names Other domain extension (sub-domain). This is the time period referred to as updating information between the Nameserver together.

If the DNS server is used to talk about the server system that has the DNS domain function, then the Name Server is the address of the DNS server cluster (DNS server).

• Obtain an IP address from the IP name of your site (your site URL without the leading 'http://'). This lookup (conversion of IP name to IP address) is provided by domain name servers (DNSs).
• Open an IP socket connection to that IP address.
• Write an HTTP data stream through that socket.
• Receive an HTTP data stream back from your Web server in response. This data stream contains status codes whose values are determined by the HTTP protocol. Parse this data stream for status codes and other useful information.

Short for Domain Name System (or Service or Server), an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4. The DNS system is, in fact, its own network. If one DNS server doesn't know how to translate a particular domain name, it asks another one, and so on, until the correct IP address is returned.

To resolve this problem, follow these steps.

1. Using the Internet Service Manager (Microsoft Management Console), open the Internet Information Server (IIS) snap-in and select the Web site reporting the 403.6 error. Right-click the Web site, virtual directory, or file where the error is occurring. Click Properties to display the property sheet for that item.
2. Select the appropriate Directory Security or File Security property page. Under IP Address and Domain Name Restrictions, click Edit.
3. In the IP Address and Domain Name Restrictions dialog box, if the Denied Access option is selected, then add the IP address, network ID, or domain of the computer that requires access to the exceptions list.
   
   In the IP Address and Domain Name Restrictions dialog box, if the Granted Access option is selected, then remove the IP address, network ID, or domain of the computer that requires access to the exceptions list.

The servers are located in the network by using it's ip address.
Using names for the domains is easier for humans.
A Domain Name Server (DNS) keeps track of the server ip address related with the domain name.
When an error occurs finding the corresponding ip address for the domain name, youll get the message "Oops! This page appears broken. DNS Error - Server cannot be found.".

DNS is the primary name resolution service for Windows Server 2003. Active Directory depends on DNS for domain controller location, and DNS influences Active Directory domain naming. Thus, to fully understand Active Directory, it helps to understand how DNS acts as an integral component in the design of Active Directory.

DNS provides Active Directory with both a name resolution service for domain controller location and a hierarchical design that Active Directory leverages to provide a naming convention that can reflect organizational structure.
Typically, a DNS domain namespace deployed to accommodate the Active Directory mirrors the Active Directory domain namespace. In cases where there is an existing DNS namespace prior to Active Directory deployment, the DNS namespace is typically partitioned for Active Directory, and a DNS subdomain and delegation for the Active Directory forest root is created. Additional DNS domain names are then added for each Active Directory child domain.
DNS data is used to support the location of Active Directory domain controllers also. During or after the creation of the DNS zones used to support Active Directory domains, the zones are populated with DNS resource records that enable network hosts and services to locate Active Directory domain controllers.

WINS is Windows Internet Naming Service, a system that determines the IP address associated with a particular network computer. This is called name resolution. WINS supports network client and server computers running Windowsand can provide name resolution for other computers with specialarrangements. Determining the IP address for a computer is a complexprocess when DHCPservers assign IP addresses dynamically. For example, it is possiblefor DHCP to assign a different IP address to a client each time themachine logs on to the network.

DNS, a.k.a Domain Name System is a database system thattranslates a computer's fully qualified domain name into anIP address.Networked computers use IP addresses to locate and connect to eachother, but IP addresses can be difficult for people to remember. Forexample, on the web, it's much easier to remember the domain namewww.amazon.com than it is to remember its correspondingIP address (207.171.166.48). DNS allows you to connect to anothernetworked computer or remote service by using its user-friendly domainname rather than its numerical IP address. Conversely, Reverse DNS(rDNS) translates an IP address into a domain name.
