网络地址

Data Link Layer of the issue of not more than, for TCP / IP network, you can use a simple arp command to check the MAC address and IP address mapping between the problem.

数据链路层的问题不多，对于TCP/IP网络，可以使用简单的arp命令来检查MAC地址和IP地址之间的映射问题。

Address Resolution Protocol or ARP is used to obtain hardware addresses of hosts located on the same physical network.

地址解析协议用于获取位于同一物理网络中的主机硬件地址。

Use an egress filter on your network to ensure that no packets leave your network with a source address that isn't a part of your internal network.

在网络中使用出口过滤器来确保没有使用不属于你的内部网络的源地址的包离开你的网络。

Vc development of the source code for network monitoring, network monitoring parameters : it text flow, current host on the network address.

vc开发的网络监控源代码，可以监控网络的相关参数：报文，流量，当前网络上的主机地址等。

Turn this one if you change the OUI# in the MAC address of your virtual machines.

如果你想使用主机的拨号网络连接连接到 Internet 或者其他 TCP/IP 网络，并且你不能给定你的虚拟机一个外部网络上的 IP 地址，通常这是让你的虚拟机访问该网络的最容易的方法。

According to the characteristics of the Kernel-Tree network, this paper proposes a new WH seamless roaming solution, which combines the IEEE802.11 protocol and the KTRP protocol, in the multihop Ad hoc network based on TCP/IP protocol stacks. The solution includes the virtual address technology, the proxy ARP in multihop Ad hoc, and the fast route-convergence technology in KTRP protocol. And its implementation for Linux is also discussed in this paper.

本文根据"核心树网络"的特点，结合IEEE802.11协议和核心树路由算法，提出"虚拟地址"技术，无线多跳网络代理ARP协议，核心树中快速路由收敛技术来共同完成基于TCP/IP协议簇的无线多跳网络中"无缝漫游"的设计方案；并讨论了在Linux操作系统下方案的具体实现。

The original purpose of DNS is to complete the corresponding exchange between domain name and address,while in order to decrease litter volume,it is not necessary to analyze all domain names in the inner networks of middle-sized and large enterprises,and hopefully the service can selectively and restrictedly react to domain name inquiry of client terminals.

0前言随着税务系统网络建设的不断发展，新的问题也在不断产生。DNS服务器分级设置，从下至上分别为县区级、地市级、省级服务器以及总局的根服务器。按照规划，它们只负责也只能解析系统网络内部的域名。但是时间一长，难免有些对外部地址的域名解析在内网传播，其结果是增加了DNS服务器的负荷，造成没有必要的垃圾流量，浪费网络带宽，降低工作效率。

Furthermore, the central idea that MAN should be built in commixing transmission mode and network structure should be layered has been established as a whole direction. In the end, the particular designing precept- includingnetwork structure, routing protocol, domain name system, IP address distribution, network security, network management, accounting, traffic engineering, network interlinking, service system implement and so on, has been analized and dissertated systemically, and the corresponding material implement precept has also been brought forward.

确定了以混合传输模式为中心、网络结构分层建设的总体设计思想；对城域网建设中详细的设计方案，包括网络结构、路由协议、域名系统及IP地址分配、网络安全、网络管理、计费、流量工程、网络互连、业务系统实施方案等方面问题进行了系统的分析与论述并提出具体的解决方案。

In further embodiments, rules may implement policies to control or limit network traffic based upon the source or destination addresses, network packet content, time of day, and the operational status and/or load of other network devices in a serial cluster.

在其它实施例中，各规则可基于源或目的地址、网络分组内容、时刻、以及串行群集中其它网络设备的工作状态和／或负荷来实现控制或限制网络话务的策略。

In the "Control Panel", double-click "Network Connections" icon and right-click in the window of the card for Internet connection, select "Properties", in the open window, double-click "Internet Protocol", Open the window, select "Use the following DNS server address" one of the main DNS service providers enter the local ISP's DNS server IP address, DNS in the auxiliary input of the network from within the current browser's IP address or DNS server IP.

在&控制面板&中双击&网络连接&图标，并且在窗口中右击用于 Internet 连接的网卡，选择&属性&，在打开窗口中双击& Internet 协议&，打开窗口后，选择&使用下面的 DNS 服务器地址&一项，在主 DNS 中输入当地 ISP 服务商的 DNS 服务器 IP 地址，同时在辅助 DNS 中输入当前内网路由器的 IP 或者 DNS 服务器地址的 IP 。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
