IP addresses are divided into ordinary addresses and special addresses. Most of the previous articles used are ordinary IP addresses, and in this article we will describe how to use the 10 methods provided by the InetAddress class to determine whether an IP address is a special IP address.First, isanylocaladdress MethodReturns True when the IP address is a wildcard address, otherwise false. This wildcard address is very much owned by computers that have multiple network interfaces, such as two

Strongloop is a powerful framework based on Nodejs that contains almost all the features needed to move the entire stack. Founded in 2013, few employees, a technology-driven, executive power team. Also in 13 I began to contact Strongloop, was to do nodejs aspects of the technical selection, saw a lot of frames, loopback is I think the coolest one. I remember thinking that Loopback's documents were too bad (mostly unlike online versions) and didn't kno

synchronization, what is synchronization? In the last article I have mentioned, no more elaboration. (similarly R1 cannot access R7, but has R7 routing entries) Solution i) Full MESH Establish the r2,r3,r5 of the whole interconnected BGP relationship. Full interconnection requires the establishment of n (n-1)/2 neighbor relationships, which is obviously inappropriate when routers are numerous. Although the theory is so, but in a small number of routers, still very effective, the use of tech

. When we look at the code we wrote two weeks ago, it's often like we saw it for the first time, so it's necessary to have a name that helps us understand its meaning. 2, even if you do not use visual Studio. NET programming, using code support files also helps improve application performance In all asp.net Web projects, such as Web applications, Web services, or Web controls, Visual Studio. NET uses code support files. The code support file makes the project better organized, modular, and more

is necessary to manually create the virtual network port on the Openvswitch Bridge and mount it in the container. Create a port-free container Start an Ubuntu container and specify that you do not create the network, and then we add the network manually. Newer versions of Docker do not allow you to modify the network configuration within the container by default, and you need to specify parameter--privileged=true when run. $ sudo docker run--net=none--privileged=true-it ubuntu:14.04 bash root@2

complete topology table is created, the router calculates the outbound route from the topology table by using the SPF algorithm based on the link bandwidth. 9. Router ID Route ID) The router ID is not the name of the router, but the identifier of the router in the OSPF routing protocol operation. In general, Loopback Interface is not configured: a virtual Interface on a vro. It exists logically and does not have this physical Interface on the vro. It

Use a simulator without a network If you use a simulator to debug a Windows CE program on a computer without a network connection, the debugging environment will prompt a "connection timeout" error after a long connection. In fact, this is because the communication between the debugging environment and the simulator adopts the network connection mode and must have available network connections. Today, with the popularity of the Internet, such requirements are nothing. However, some people may ne

changes may be made to the parameter file in the folder, and thenWhen the IP address is B, it is started through the B folder. In the past, when the IP address is a, the parameter is gone, because when the IP address is a and the IP address is B, two folders are set according to your method, when one of the operations is used, the corresponding file must be changed.Without changing the other, you may not understand what you are talking about.After a long time of searching and asking, I finally
