  1. 1. Domain Names & Web Hosting By: SZ Quadri CEO, Zaidsoft www.zaidsoft.com [email_address]
  2. 3. Launching the web site Related To Question Web Hosting Where my Web site contents will reside (to be served to the user’s browser)? Domain Name What name people will use to access my site? E.g., mySite.com
  3. 4. Browser & Server <ul><li>From Browser -------  Get me yahoo.com home page (Request) </li></ul><ul><li>From Server  --------- Here is index.html (Response) </li></ul>Request Internet Infrastructure Web Browser Server Response
  4. 5. Domain Name <ul><li>Domain Name: The unique name that identifies an Internet site. Domain Names always have 2 or more parts, separated by dots. Example: yahoo.com or yahoo.co.in </li></ul><ul><li>The part on the left is the most specific, and the part on the right is the most general. </li></ul><ul><li>Many machines can be pointed using the same domain name by qualifying the domain name with host name like www.ibm.com and mail.ibm.com </li></ul><ul><li>Internet Protocol does not know about the domain names. </li></ul><ul><li>The server which translates name into IP address is called “Domain name server” or “Name server”. </li></ul><ul><li>For every domain name you need at least 2 name servers. </li></ul><ul><li>Name servers also have names like ns1.zaidsoft.net and ns2.zaidsoft.net </li></ul>
  5. 6. Domain Life Cycle
  6. 7. Domain To IP <ul><li>Mapping domain names to IP addresses </li></ul><ul><li>The mapping of names to addresses consists of independent, cooperative </li></ul><ul><li>systems called name servers. </li></ul><ul><li>A name server is a server program that holds a master or a copy of a name-to-address mapping database, or otherwise. </li></ul><ul><li>points to a server that does, and that answers requests from the client software, called a name resolver. </li></ul>
  7. 8. Domain Whois <ul><li>Records that show “who is” responsible for various aspects of a particular domain name. This includes various contact details such as Registrant (owner), Admin, Billing. </li></ul><ul><li>Registrant is considered legal owner of the domain name. </li></ul><ul><li>Domain management password can be used to do almost everything related to a domain name including changing the ownership of the domain name. </li></ul><ul><li>Example whois Record: </li></ul><ul><li>Domain Name: ZAIDSOFT.NET </li></ul><ul><li>Registrant: </li></ul><ul><li>ZAIDSOFT </li></ul><ul><li>SZ Quadri (*****@zaidsoft.com) </li></ul><ul><li>Civil Lines </li></ul><ul><li>Allahabad UP, 211001 IN Tel. +91.5322607076 </li></ul>
  8. 9. Domain Name and Trade Mark <ul><li>A domain name, apart from being your worldwide address, is your own unique identity on the web. </li></ul><ul><li>The Bombay High Court has held that the Internet domain names are of importance and are a valuable corporate asset. (As in the case of Rediff Communication Limited Vs Cyberbooth) </li></ul><ul><li>One should protect our trade mark (name) online by registering domain name(s) representing the trade name. </li></ul><ul><li>Business.com was sold for roughly US$ 7 million. </li></ul>
  9. 10. The Uniform Domain-Name Dispute Resolution Policy (UDRP) <ul><li>The Uniform Domain-Name Dispute Resolution Policy (UDRP) has been adopted by ICANN-accredited registrars in all gTLDs (.aero, .biz, .com, .coop, .info, .museum, .name, .net, .org, .pro). Dispute proceedings arising from alleged abusive registrations of domain names (for example, cybersquatting) may be initiated by a holder of trademark rights. </li></ul>
  10. 11. Internet <ul><li>The network of networks. </li></ul><ul><li>The Internet is marvelously robust, with thousands of independent networks operating together to move traffic around the globe. </li></ul><ul><li>Works on well defined protocols. </li></ul><ul><li>TCP/IP is the primary protocol set. </li></ul><ul><li>IP stands for Internet Protocol. </li></ul><ul><li>IP defines how data can travel from one machine to another in the form of a packet. </li></ul><ul><li>Every machine has unique IP Address. </li></ul><ul><li>An IP address is the numerical address of a computer on the Internet. Each IP address consists of four numbers separated by periods. </li></ul><ul><li>Examples of IP addresses are: 192.168.0.222 </li></ul>
  11. 12. IP Packet
  12. 13. IP Address <ul><li>ICANN </li></ul><ul><li>The Internet Corporation for Assigned Names and Numbers (ICANN) is the nonprofit organization that was formed to assume responsibility for the IP address space allocation, protocol parameter assignment, domain name and root server management functions. </li></ul><ul><li>ICANN suggest ISPs should consider the following order of priority when seeking IP addresses: </li></ul><ul><li>1) Request IP address from upstream provider. </li></ul><ul><li>2) Request IP address from provider's provider. </li></ul><ul><li>3) Request IP address from ARIN or your RIR. </li></ul>
  13. 14. Regional Internet Registries (RIRs) <ul><li>The Regional Internet Registries (RIRs) are responsible for allocating and assigning IP addresses to ISPs, organizations and end users in their designated geographical regions. </li></ul><ul><li>There are five RIRs - each serving specific geographical areas worldwide. These include APNIC, ARIN, LACNIC, RIPE NCC and AFRINIC. </li></ul><ul><li>APNIC </li></ul><ul><li>Asia Pacific Network Information Centre (APNIC) is responsible for IP distribution in the Asia and Pacific region. </li></ul><ul><li>It is a not-for-profit, membership-based organization whose members include Internet Service Providers, National Internet Registries, and similar organizations. </li></ul>
  14. 15. Web hosting options <ul><li>You can host your web </li></ul><ul><li>site in 3 ways : </li></ul><ul><li>1. Virtual Hosting </li></ul><ul><li>2. Virtual Dedicated Hosting </li></ul><ul><li>3. Dedicated Server Hosting </li></ul>
  15. 16. Virtual Hosting <ul><li>Share or Virtual Web Hosting is a solution that allows a you to rent part of a web server to store your website's data, rather than pay for an entire dedicated server with more space and power than you need. With share web hosting basically you are sharing same server and IP address (not domain name) with other web site. Share web hosting is much cheaper as compare to dedicated servers. </li></ul>
  16. 17. Advantages of Virtual Hosting <ul><li>Allows a user to share server cost with other users i.e. it is affordable. </li></ul><ul><li>Fulfills the requirements of small sites. </li></ul><ul><li>Complete control over your own applications. </li></ul><ul><li>Allows the server administrator to maximize his resource usage by resource-sharing among the websites. </li></ul>
  17. 18. Disadvantages of Virtual Hosting <ul><li>Users get limited rights on the server. </li></ul><ul><li>Users have restrictions on the server resource usage . </li></ul>
  18. 19. Dedicated Hosting <ul><li>In dedicated hosting a complete server is owned by one owner. As an owner of the dedicated server, he has full control of every aspect of the hardware and software. </li></ul>
  19. 20. Advantages of Dedicated Hosting <ul><li>Full control in the hands of user . </li></ul><ul><li>Performance is greatly enhanced. </li></ul><ul><li>Security is greatly enhanced. </li></ul><ul><li>Provides enhanced scalability. </li></ul><ul><li>Complete flexibility over the choice of software and hardware . </li></ul>
  20. 21. Disadvantages of Dedicated Hosting <ul><li>Quite expensive and unaffordable for normal users. </li></ul>
  21. 22. Virtual Dedicated Hosting <ul><li>It is more than a shared server and less than a dedicated server. </li></ul><ul><li>A VPS simply put is, a server that runs inside another server. </li></ul><ul><li>Each VPS looks, feels, and acts like a dedicated server but shares the same hardware. </li></ul>
  22. 23. Advantage of VDH <ul><li>Allows users to have dedicated hosting environment at the cost of Shared Hosting. </li></ul>
  23. 24. Difference Put Together
  24. 25. Data Centers <ul><li>Data centers provide secure facilities for housing telecommunications and computer equipment. Offering safety, security, access and a suitable environment, data centers typically accommodate thousands of servers. </li></ul>
  25. 26. Can I host my own Server ? <ul><li>Theoretically </li></ul><ul><li>YES </li></ul><ul><li>but Practically </li></ul><ul><li>NO </li></ul>
