subnet address range

is in the back. The subnet mask is used to distinguish and calculate the IP address. For example, if the subnet mask of ip192.168.1.1 is 255.255.0, the network address is 192.168.1.0 and the host address is 0.0.0.1. Gateway So what is the gateway? A gateway is essentially

The following small series for everyone to bring an article WinForm C # get the MAC address, IP address, subnet mask, the default gateway instance. Small series feel very good, now share to everyone, also for everyone to make a reference. Let's take a look at it with a little knitting. 1. Add an assembly 2. Introduce namespaces Using System.Management; 3.

Technorati label: Subnet Mask, Network Subnet Mask and network address A valid broadcast address is the network address of the host plus the largest host number. The network address is obtained by bitwise AND the machine's IP

The simplest understanding is that the respective IP addresses

You must know something about the IP address, right? We know that the TCP/IP protocol that is widely used in the Internet is to differentiate between different hosts by using IPs. If you've ever had a TCP/IP protocol set up, then you're bound to encounter the term subnet mask (Subnet mask), so do you know what a subnet

_mask = "255.255.255.0"; $ip = Ip2long ($ip _addr);$NM = Ip2long ($subnet _mask);$NW = ($ip $nm);$BC = $NW | (~ $nm); echo "IP address:". Long2ip ($IP). "\ n";echo "Subnet Mask:". Long2ip ($NM). "\ n";echo "Network Address:". Long2ip ($NW). "\ n";echo "Broadcast Address:".

IP is something that everyone is very familiar with! But there must be something you do not know, yes, I am the popular science you do not know the Linux Kang brother. In our OSI seven layer model in the network layer will break into the IP header, record our IP address, then IP exactly how many bits? How big is the range?0.0.0.0-255.255.255.255--This is the range
