试题来源: 解析 MAC地址空间:2^48IPv4地址空间:2^32IPv6地址空间:2^128 MAC地址由48位组成,因此地址数量为2的48次方。IPv4地址长度为32位,地址空间为2的32次方。IPv6地址长度为128位,地址空间为2的128次方。题目完整且有明确答案,无需舍弃。反馈 收藏 ...
NOTE Although NAT works well in practice, remember that it’s essentially a hack used to extend the lifetime of the IPv4 address space. In a perfect world, we would all be using IPv6 (the next generation Internet) and using its larger and more sophisticated address space without any pain....
The router is also connected to the Internet—the cloud in the figure. Because the router is connected to both the LAN and the Internet, all machines on the LAN also have access to the Internet through the router. One of the goals of this chapter is to see how the router provides this...
How big is the MAC address space? The IPv4 address space? The IPv6 address space? How many hexadecimal bit strings of length 14 have more A's than B's? Explain IPv4 Versus IPv6. How many bit strings have an equal number of 0's and 1's?
When a microburst exceeds the forwarding capability of a switch, the switch buffers the burst data for transmission later. If the switch does not have sufficient buffer space, the excess data is discarded, causing congestion and packet loss. The following figure shows a typical millisecond-level...
With the recent exhaustion of the IPv4 address space, the question of IPv6 adoption is gaining importance. More end-users are getting IPv6 prefixes from their ISPs, more websites are reachable via IPv6, hosting companies start billing for IPv4 connectivity or give discounts for IPv6-only host...

2. Assume that Computer A has an IP address How big is the MAC address space? The IPv4 address space? The IPv6 address space? (a) What information do IP addresses provide? (b) What is the binary form of the IPv4 address 192.168.46.20? (c) What is the role of a subnet mask? IP...
How is the IPV4Address Computer attribute populated? How is the logon hours attribute set in Active directory (windows server 2008 r2) ? How long can a DC be offline before it begins to affect the entire AD topology? How long can a DC be offline? How long can a domain be shut down ...
A subnet mask is a number that specifies which parts of anIP addressrepresent the host and network portions of the address. These masks are 32 bits in IPv4 networks and 128 bits in IPv6 networks. A subnet mask is initially written in binary format, with network bits ...
