Internet useAn Internet service provider, ISP, is provided with a unique URL access address. This address is a unique number. The number for each ISP is stored within a DNS server. The DNS servers interpret the ISP URL Domain name and provide the appropriate IP address number. The Domain is under the control of a specialised computer, called a PDC, (primary domain controller).[2] This computer holds records of all the user accounts within the domain, their rights to access information, and lists of approved System Operatives. This PDC is backed up by a SDC, (a secondary domain controller), this computer synchronises itself with the PDC and takes over the role in the event of a PDC failure.[3] Multiple replication servers connect to these control computers and they are routed to the Internet backbone to provide the requested data to and from the domain.[4] Communication protocolsInternet protocols that are focused on inter-domain functions include: Border Gateway Multicast Protocol, Classless Inter-Domain Routing, Multicast Source Discovery Protocol, and Protocol Independent Multicast. ServicesA PDC uses a number of special computer programs to announce its presence to other domain controllers. It uses Windows Internet naming service WINS[5] and Browser[6] services to allow other computers to gain access to digital information that it has control over. OtherThe opposite of inter-domain routing is intra-domain routing: Routing within a domain or an autonomous system.
