subnet converter

Struts2 registers a local converter and a local Converter To implement a custom converter, You need to inherit the defatypetypeconverter class or the StrutsTypeConverter class from the objects to be converted, and obtain the entry of a type converter to implement the developer's own type

Typeconverter class. The description in msdn provides a unified method to convert the value type to other types, as well as access standard values and sub-attributes.Let's take a look at the example to translate a string into a type converter with a point structure.Public class pointconverter: typeconverter {Public override bool canconvertfrom (itypedescriptorcontext context, type sourcetype ){If (sourcetype = typeof (string) {return true ;}Return bas

TCP transmission: Use the socket service to implement a text converter, socket Text Converter Reprinted please indicate the source, thank you: http://blog.csdn.net/harryweasley/article/details/45665291 I recently read a teaching video and learned socket programming. There is an example in which I feel that it is well written. I will organize it here to help me recall and view it. Requirement: Text

The network does not pass, this is the most network problem table image, but if you can access me, but I can not access you, this problem is more troublesome. This article is the author in the actual combat in a subnet mask caused by the fault summary. The network is a phenomenon that often occurs, encounter this phenomenon, I believe many people will focus on network cable, NIC driver, network card parameters, while checking the network card paramet

object to a string in some way. To achieve these transformations, there is a magician in Struts 2.0 who can help you--converter. With it, you don't have to repeat this code over and over again: Date birthday = dateformat.getinstance (dateformat.short). Parse (strdate); OK, now let's take a look at an example. Converters--hello World At the end of my last article, "Internationalizing in Struts 2.0 (i18n) Your application," I gave an example tha

. Therefore, any IP address whose first byte is greater than 223 or less than 240 is a multicast address. Each byte of the IP address is 0 ("0.0.0.0") and corresponds to the current host; each byte of an IP address is 1. The IP address ("255.255.255.255") is the broadcast address of the current subnet. All IP addresses with "11110" are reserved for future use; the IP address cannot start with "12 7", 127.1.1.1 is used for loop testing, and the first e

Subnet division definition: Internet organizations define five IP addresses, which are A, B, and C. There are 126 Class A networks, and each class A network may have 16777214 hosts, which are in the same broadcast domain. It is impossible to have so many nodes in the same broadcast domain. The network will be saturated due to broadcast communication. As a result, most of the 16777214 addresses are not allocated. You can further divide a class-based IP

Subnet Mask:What is a subnet mask subnet mask cannot exist alone,It must be used in conjunction with an IP address. The subnet mask has only one effect,is to divide an IP address into two parts: network address and host address.The subnet mask setting must follow certain rul

The subnet mask (subnet mask) is also called the netmask, address mask, and subnet mask, which is used to indicate which bits of an IP address identify the host's subnet and which bits identify the host's bitmask. The subnet mask cannot exist alone, it must be used in conjun

The previous section mainly focused on understanding the theory of IP addresses and subnet division. This section is used to analyze specific instances. This exercise is also found on the Internet and I feel pretty good. Okay, now. Instance analysis 1. 192.168.1.0/24 use the subnet mask 255.255.255.240 to divide subnets. The number of available subnets is (), and the number of available host addresses in ea

Original article title: IP subnetting made easy Address: http://articles.techrepublic.com.com/5100-10878_11-6089187.html IP network engineers need to have a solid understanding of how IP subnet division works. however, this topic is often ignored by instructors and the students are very confused and nervous about it. george ou developed a simple, graphical method to explain IP subnet division in a simple a

After an organization applies for an IP address, it may need to further divide the IP address into subnets. For example, a large company applies for a Class B IP address 166.133.0.0. If you use the standard subnet mask 255.255.0.0 without further dividing subnets, all hosts in the 166.133.0.0 Network (a maximum of 65534 hosts) will be in the same broadcast domain, A large number of broadcast data packets in the network will make the network unavailabl

Fast subnet division method subnet division basics: subnetting advantages: 1. reduce network traffic 2. improve Network Performance 3. simplified Management 4. how to Create a subnet that is easy to expand the geographical scope: how to divide subnets? First, you must note that the power of 2: The power of 2 0 to the power of 9 are: 1, 2, 4, 8, 16, 32, 64,128,256

Subnet mask (Subnet masks): The subnet mask is used to identify which part of the IP address is a network address. Which part is the host address, there are 1 and 0 components, long 32 bits, all 1 of bits represent the network number. Not all networks require subnets, so there are 1 concepts: The default subnet mask (
