The Code is as follows:
Function checkIP){Obj = ip;Var exp =/^ (\ d {1, 2} | 1 \ d | 2 [0-4] \ d | 25 [0-5]) \. (\ d {1, 2} | 1 \ d | 2 [0-4] \ d | 25 [0-5]) \. (\ d {1, 2} | 1 \ d | 2 [0-4] \ d | 25 [0-5]) \.

Python: a simple method for converting the subnet mask and a python Subnet Mask
This article describes how to convert the subnet mask in Python. We will share this with you for your reference. The details are as follows:

The subnet mask cannot exist alone, it must be used in conjunction with an IP address. The subnet mask has only one function, which is to divide an IP address into two parts: network address and host address.The subnet mask settin
As for subnet division, the subnet mask is odd. 1.0.1.0 -- 1.0.3.255 Fujian Telecom converts the subnet mask to an IP segment 1.0.1.0/24--1.0.2.0/23, if two IP addresses are replaced by binary IP addresses in a general way, or the budget is 0001.00000000.00000001.00, the
gateway in the DHCP server, then all the computers on the network obtain the IP address of the new default gateway. This method is applicable to networks with large network sizes and variable TCP/IP parameters. Another way to automatically obtain the gateway is to automatically obtain the Gateway by installing the agent server software (such as MS Proxy) client program. Its principles and methods are similar to those of DHCP. Due to space limitations, we will not go into detail.Through a simple

Subnet Mask, the concept and working principle of the gateway and ARP Protocol are several important knowledge points that Beginners first encounter when learning network knowledge, among them, the role and basic working principle of subnet mask and ARP protocol is also the key and di
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.

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 th
