subnet mask on router

Subnet Mask is the basic knowledge that each network administrator must master. Only by mastering it can you truly understand the TCP/IP protocol settings. The following describes what a subnet mask is. IP address Structure To understand what a subnet

PrefaceThis document is simply a logical algorithm, and how to compute network bits, host bits, and broadcast addresses in the case of known IP addresses and subnet masks. All steps are far from the most primitive binary way, the direct hit principle, please read carefully.1. Logic algorithmLogic and operations and logic or operations are used when computing network bits, host addresses, broadcast addresses, so it is necessary to understand their algo

IP address Structure To understand what a subnet mask is, you must understand the composition of IP addresses. The Internet is composed of many small networks, each of which has many hosts, thus forming a hierarchical structure. When designing an IP address, considering the hierarchical features of Address Allocation, each IP address is divided into two parts: the network number and the host number to faci

: 000000000.oC: 255.255.255.0 You can use a subnet mask to determine the network number and host number of an IP address. You can use the IP address and the corresponding subnet mask to calculate the network number and host number.For example, 10.68.89.1 is a Class a ip address. Therefore, the default

, infrared, etc., sometimes referred to as physical media. The MAC address is also called the physical address, hardware address, or link address, which is written by the network device manufacturer when it is produced inside the hardware. This address is not related to the network, that is, regardless of the hardware with this address (such as network cards, hubs, routers, etc.) access to the network where, it has the same MAC address, MAC address is generally immutable, can not be set by the u

Have always felt that the internet is a magical thing, in the use of the time is also very confusing, you think?Have you ever wondered: what does a subnet mask do? Why is it as if it can be configured to surf the Internet (of course, now sometimes it seems to be a spell of luck)?Pre-Knowledge: Windows View routing commands:Route print The route is mainly divided into: (detail reference: http://blog.

are suitable for small networks such as campus networks, and each class C network can have up to 254 hosts. From the above introduction we know that the IP address is the network number and host number to indicate the host on the network, only in a network number under the computer can be "directly" interoperability, computers with different network numbers need to be connected through gateways. But such a division appears and is very inflexible in some cases. For this reason, the IP network

Network Segment Encyclopedia business cards A cidr Block refers to the part in a computer network that uses the same physical layer device (transport medium, repeater, hub, and so on) for direct communication. From one IP address to another, it is like a network segment from 192.168.0.1 to 192.168.255.255. Network Segment The subnet mask assigned by the IP address is only 255 or 0 in each segment by defa

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

First of all, our premise is the local area network, so we mentioned the modification more specifically, is to find the subnet mask and the default gateway for proper padding. Here are two specific ways to do this: Method One, we find any other networked computer on the same LAN, locate and double-click the local connected Internet Protocol (TCP/IP) entry, and populate the

Subnet mask (subnet mask) definitionIt is a bitmask that indicates which bits of an IP address identify the subnet on which the host resides and which bits identify the host. The subnet mask
