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?
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....
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...
We won’t go into a tremendous amount of detail, though, because after you see the big picture, NetworkManager and other configuration systems will be more transparent 在基于Linux的系统中,有几种自动配置网络的方法。 在台式机和笔记本上,最常用的选项是NetworkManager。 其他网络配置管理系统主要针对较小...
The IPv4 address space was designed in the late 1970s, and it seemed impossible to exhaust. However, addresses were not allocated in a way that anticipated changes in technology and an explosion in the number of hosts on the Internet. The IPv4 address space was consumed to the point that,...
This is how one machine can find another through the massive network. The version of IP most of us use today is IPv4, which is based on a 32-bit address system. There's one big problem with this system: We're running out of addresses. That's why the Internet Engineering Task Force ...
Arabic characteres is display with symboles and not understand and not clear why or what change in code arabic datetime format Are static classes thread safe? Are there any (simple) methods/libraries to recognize similar pictures using C# code? Are there any BIG commercial apps using .NET fr...
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 ...
