How DNS Works.DNS Namespace.• Hierarchical name space.• Each node in tree represents.domain/subdomain.• Some subdomains are defined.as zones.• Each zone has a “primary”.name server responsible for.all lower nodes.• Resource records (RR) are defined.for each node.• Example RRs are: Address (A),.pointer (PTR), mail exchange (MX),.name server (NS), start of.authority (SOA)

Trong phần này chúng ta sẽ tìm hiểu về TCP/IPv4. IPv4 có 32bit chia thành 4 Octet ( mỗi Octet có 8bit, tương đương 1 byte ) cách đếm đều từ trái qua phải bít 1 cho đến bít 32, các Octet tách biệt nhau bằng dấu chấm (.), bao gồm có 3 thành phần chính. - Class Bit: Bit nhận dạng lớp dùng để phân biệt địa chỉ IP thuộc lớp nào. - Network ID: Địa chỉ của mạng - Host ID: Địa chỉ của máy..Như vậy với một số IP được viết dưới dạng nhị phân ví dụ...

This lab exercise helps develop an understanding of IP addresses and how TCP/IP networks operate. It is primarily a written lab exercise. However, it would be worthwhile to review some real network IP addresses using the command line utilities ipconfig for Windows NT/2000/XP or winipcfg for Windows 9x/ME. IP addresses are used to uniquely identify individual TCP/IP networks and hosts, such as computers and printers, on those networks in order for devices to communicate.

You are told that the Ethernet in the previous example must provide address space for at least 500 hosts. A second.Ethernet, shown in Figure 2, will interconnect Bay and Chives, and must have address space for no more than 126.hosts. Develop a configuration that shows appropriate subnetting.

Cable a network similar to the one in the previous diagram. Any router that meets the interface.requirements may be used. Possible routers include 800, 1600, 1700, 2500 and 2600 routers, or a.combination. Refer to the chart at the end of the lab to correctly identify the interface identifiers to be.used based on the equipment in the lab. The configuration output used in this lab is produced from.1721 series routers. Any other router used may produce slightly different output.

In Chapter 11, you were introduced to two advanced routing protocols: OSPF and EIGRP..Both of these protocols are classless protocols that support advanced IP addressing concepts,.including variable-length subnet masking (VLSM) and route summarization. This chapter.focuses on these two advanced concepts.

The Transmission Control Protocol/Internet Protocol (TCP/IP) is a standard.that includes many protocols. It defines how machines on an internetwork can.communicate with each other. It was initially funded by and developed for DARPA.(Defense Advanced Research Protects Agency), which is a conglomeration of U.S. military and.government organizations. Developed initially for the government, it was later made available.to the public, mainly seen on Unix systems.
