netmask address

In Linux, obtain the IP address of the specified network and the interface of netmask: Int get_ip (char * ipaddr, char * netmask, const char * ethname){Int ret =-1;If (ipaddr & netmask & ethname){Int FD, intrface;Struct ifreq Buf [16];Struct ifconf

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

Natmask is the subnet mask, and the IP with the operation, to get a domain.IP consists of 4 segments, example 172.25.45.10 each segment consists of a 8-bit binaryThat is, 11111111.11111111.11111111.11111111, this represents 255.255.255.255.The same

What is the difference between 192.168.2.1/24 and 192.168.1.1/24?     Is two different network segments, the subnet mask is 24,The first value range is 192.168.2.1 ~ 255,The second value ranges from 192.168.1.1 ~ 255These are two CIDR blocks. The
