3. query the network details to display the IP address. The
At present, the more authoritative public DNS server providers have the Opendns,google-Dns,norton DNS, what are the actual access speeds of these DNS servers? This is directly related to the speed of our Internet access, after all, the fast speed is the king. The author comp
Some time ago, I changed the server to using ipfilter + ipnat + dhcp -- ipfilter + ipnat packet filtering, forwarding, and DHCP server architecture notes under freebsd5.4. However, I recently felt that the server is always offline, I opened another dns Cache service on the server
In the previous section we talked about the auxiliary and stub areas, so let's take a closer look at them. One, the auxiliary area About creation and functionality of secondary zones I'll explain in more detail by creating a secondary server, and I'll start working on the relevant preparations. The first two virtual servers to create a basic configuration (due to previous knowledge of the explanation, here is no longer detailed) example: computer name
computer access the Internet? Open the "local connection" attribute of the network management station, check the network settings, and find that the preferred DNS server is "202.99.160.68", and the alternative DNS server is "202.99.166.6 ", the DNS of several other servers

As we all know, Linux does not catch up with Windows popularity and ease of use on desktop applications, but it is precisely because of its seemingly troublesome command-line operations that make it more secure than Windows, which uses a graphical interface for ease of use, This makes Linux a very popular server, especially with the well-known Apache lamp and DNS server
Frequent internet friends may often go to Sina, Sohu and other large websites, only need to enter their web site in the browser to achieve access, it seems very simple, but technically speaking, but contains a complex process: in the Web page, first in the browser input site domain name, Then the browser will be based on the local DNS server settings will be entered into the site domain name to the correspo

More than two servers to work together must involve load balancing problem, the current commonly used load balancing technology are: NAT load balancing, reverse proxy load balancing and DNS load.
NAT load Balancing maps an external IP address to multiple internal IP addresses, dynamically converts each connection request to an internal server address, and leads the external c
hierarchy, and any one domain is at most one parent domain, but can have multiple or no subordinate domains. You cannot have the same subordinate domain or host name in the same domain, but you can have the same subordinate domain name or host name in different domains.
