Where "Set DNS" is a dedicated command for setting up a DNS server, "Static" means setting up a static DNS server, and "[addr]" is the specific DNS server IP address.For exam
address that identifies a computer network interface that connects Interent or some dedicated intranet. These addresses are called unicast addresses , and other types of addresses include broadcast, multicast, and anycast addresses, which may involve multiple interfaces and some special-purpose addresses.When the Interent address structure is initially defined,
; you can restrict Internet traffic when the bandwidth is narrow. You can disable access to some websites. In this case, proxy servers are more suitable for Internet shared access over large and medium-sized networks than NAT alone. However, the disadvantage of using a proxy server is that an additional server is required. In addition, the proxy server settings are complicated. However, considering the specific internal application of the organization, using the proxy server is the most appropr

Our network was built using VPN, and many office sites used a unified office platform. At that time, this problem also occurred during VPN set
A few days ago, the new computer Nic cannot get an IP address. I started to think it was a driver problem. Later I went to the Asus Chinese forum to ask for advice. I installed the driver to solve a problem that could not be identified by the device. It seems that the NIC could also get the IP address at that time.

Multilayer Switching (MLS) is an Ethernet-based route exchange technology that provides a layer-3 Switch with an existing router. This article includes IP-only MLS; ipx mls and multicast MLS are out of the scope of this article.
A traditional router typically performs two main functions: rewrites the Media Access Control (MAC) address based on the route table and information packet exchange route processing
The reason why an intranet computer can access the Internet through a vro is that the vro is assigned an IP address that gives the computer an identity. If the vro cannot assign an IP address to the computer, then we cannot access the Internet.

Now my retreat is coming to an end. According to the initial plan, I plan to spend about a month studying JavascriptCodeObfuscation. Later, as the engine of Google App Engine is being studied more and more deeply, and code obfuscation is more complicated than I thought, I canceled the plan to study code obfuscation, focus on website-related research.
This article introduces three Rest interface services that I implemented on Google App Engine:
1. query the service of administrative divisions
Why does the computer automatically get an 192.168.0.1 address? Under what circumstances will the computer be able to move its 192.168.o.1 address? First, there is a DHCP server in the network, which is dynamically assigned IP address by the DHCP server for the computers within the network; The
common one is NAT (Network Address Translation), a computer in a sub-Network, only a few hosts (usually only one) can directly connect to the Internet. IP addresses of hosts in different subnets can be repeated. When computers in the subnet need to access the Internet, they need to be "forwarded" by computers directly connected to the Internet in the subnetwork ".
Although it seems that NAT is good, it can

Ip rule add to 192.168.10.xxpref 10001 table NET10
If the destination IP address is 192.168.10.xx, the NET10 route table is used temporarily.
In this way, will there be security problems? If the route changes, will they access the private network?
No, because the routing rule is to 192.168.10.xx, that is, when the target is 96, the route is used. T
