Modern applications often need the ability to learn information about the "hosts out" on the network. One key class in this process for Java developers is the java.net.InetAddress . This class allows the various information about the hosts, as well
Summary:
Class A, B, C is actually the concept of address block, the so-called application of a class C address, refers to the application of a Class C address block.
C class Address block of specific IP address of this class C address block, of
The IP address is like a phone number, but the area code is required for dialing a phone number from another country. The subnet mask is required for accessing other network segments in the network. The IP address must be classified as if the IP
(1) restrict name server recursive query
Disabling recursive queries can enable the name server to enter the passive mode. When it sends a query request to an external DNS, it will only answer the query request for its authorized domain, instead of
The current IP address uses a 32-bit address, represented in dotted decimal format, for example, 172.16.0.0. The address format is: IP address = network address + host address or IP address = Host address + subnet address + host address.When the IP
Today the IP network uses 32-bit addresses, dotted decimal format, such as 172.16.0.0. Address format: IP address = Network address + host address or IP address = host address + subnet address + host address.IP Address TypeWhen the internet was
First, what is a subnetThe IP address consists of two parts, the network ID and the host ID. The network number identifies a subnet on the internet, and the host number identifies a host in the subnet. A subnet is a smaller network that is based on
IP address, subnet mask, default gateway, preferred DNS server, and backup DNS Server
IP address
The IP address is the identifier used by the computer in the network when accessing the Internet. This identifier is unique globally. The IP address
When talking about the Internet, IP addresses cannot be mentioned because IP addresses are a very important concept from the perspective of learning and using the Internet, many INTERNET services and features are reflected by IP addresses.

Over the past 20 years, network technology has continued to develop, from the initial X.25, frame relay, to Ethernet, FDDI, to the popular ATM, different technologies provide diverse network options. To achieve network interoperability among various

I. Summary
The concept and function of subnet mask
Third, why do I need to use the subnet mask
Four, how to use the subnet mask to get network/host address
Five, the classification of subnet mask
VI.
There are two ways to compute the subnet mask:
Method One: Use the subnet number to calculate:
1. First of all, the number of subnets from the decimal number into binary number;
2. Then, the number of digits of the binary number obtained by the
IP subnet addressing
All Hosts must support subnet addressing (rfc950 [mogulandpostel1985]). IThe P address is simply composed of a network number and a host number. Instead, the host number is divided into a sub-network number and a host number.The
