| Domain name servers function as a directory service for classifying and redirecting requests for specific websites in an IP host or domain name servers. Domain names, when you ask for a website's address, normally the website's domain name server will return an address which cannot be resolved, it uses the DNS for finding the specific server's name servers to respond to the request. The server address as a label for your domain. There are two types of domain name systems - the single-vlan private network (or STP) and multi-vlan private network (or MPLS). STP operates on a class of service model and assumes that the domain name is within a domain only. Multi-VLAN is based on a service provider model and multiple vlans are tied together with IP based service Provider networks. In a traditional two-vlan private network, each virtual LAN would have its own IP address and would use the same port for all devices. In a STP, different virtual LANs within a domain have their own IP addresses and would be able to inter-querade with each other as to avoid conflicts. A private phone service using a private domain name and private network will allow people to establish voice communication in areas where typical VoIP calling is impossible. The most popular application of IP-based voice communications is voice over IP, also known as VoIP (Voice Over Internet Protocol). Most Internet phones still use the traditional PSTN lines that originated the service. The main difference today is that IP phone calls use digital protocols instead of analog ones as well as packet switching rather than cable connections. If an Internet user wants to send an email message from his computer to another IP address, he will probably do it by either using an email client or the command line interface usually included with Windows like CMD or WinINET. But if the user wants to send the same message via the IP address, he can use the "ddns" command prompt which is a web-based tool that connects to the DNS servers and dynamically creates or modifies the IP addresses associated with the domain name. For example, when a.com domain name is typed into the web browser, an IP address derived from the DNS server is then generated. The resulting IP address is then sent as an email message to the recipient. One of the advantages of using the DDNS technique is that it saves time and money. There is no need for a static IP address because it is dynamically created on the fly based on the details of the domain name and its extensions. This means that each time you connect to the internet, your IP address and corresponding DNS server is updated. In addition, you do not have to reconfigure your router or modem since the details of the IP address and DNS server are always in your control panel. This is the reason why so many network administrators prefer to use the firmware based netfaster iad 1.0 for their routers and servers. Another advantage of this internet protocol was codenamed Netflow and is an ingenious filtering mechanism that is based on the same technology that is used in the netbook. Netflow is a mechanism designed by Cisco to filter the data that passes across an IP connection. The first generation of Netflow was referred to as G.711 codec and is the one that most experts recommend. The G.711 Netflow algorithm was designed by Avirach Kameez and Michael J. Cafarella which are two leading expert developers of the netflow software. The new Netflow 2.x series improves on the capabilities of the first generation and includes some amazing features like support for more advanced packet types, security enhancements, faster packet processing, better real-time performance and much more. Another good alternative to using a static IP address is using an internet protocol address (IP) through a domain name. There are a few advantages to using an IP address other than just preventing unauthorized access. First, by establishing an IP address, you can configure the scope of your network. The result is that you can set up the internet protocol for any purpose, including allowing access from a computer in a different part of the world to a domain name within your own local area. The other advantage is that you can establish different IP sub-faces within your corporate intranet system. To access the internet using an IP address and DNS you need a domain name and a domain registrar server. Your domain name and registrar server should be from the same IP block. If they are not, you might experience problems. These include communication problems as well as poor performance from your web browser. To test this issue, you can create a website in My Computer and then visit it from an IP address of your choice; your connection should be fine. |
