TCP / IP protocol and configuration
- TCP / IP protocol suite: is the most widely used set of communication protocols,
including standard protocols for Internet applications in a large number of
support across the network infrastructure, communications across operating system platforms - Between the host and the host three elements of the communication:
IP address (address): a network identifier of each node of the network address of the
subnet mask (subnet mask): distinguish the network and host bits, to determine whether the IP address belong to the same network
IP routing (router): a data communication path selection - Composition IP address (dotted decimal)
a total of 32 binary bits: the network host bits
11000000.10101000.00000001.00000000 /11111111.11111111.11111111.00000000
converted to decimal number 4, spaced:. 192.168.1.0/24 (255.255.255.0)
IP address version: ipv4 square of the total number of 32
128 ipv6 square of the total number of - IP address classification
Class A: 001--127 master. the Lord. Main = "Subnet Mask: 255.0.0.0 (which is the loopback address 127.0.0.0)
Class B:. 128--191 mesh. the Lord. Main => subnet mask 255.255.0.0
C class: 192--223. network. network. Main = "Subnet Mask: 255.255.255.0
D class: 234--239 multicast address
category e: 240--254 Research address
the private network address of the LAN address :()
A: 10.0.0.0-10.255.255.255 /. 8 ( wherein the network address 10.0.0.0/8: 10.255.255.255/8 indicates the broadcast address)
B: 172.16.0.0-172.31.255.255 / 16
C: 192.168.0.0-192.168.255.255 / 24
the Tip: network address is not on the public network transmission
public address: the rest is money to pay rent temporary address NIC (public address can also be used as a host address)
loopback address: test the machine TCP / ip special (127.0.0.1-127.0.0.254)
Second, configure IP addresses - Open the Network and Internet settings - configure the network adapter - select the card you want to configure - Right Properties - Double-click Internet Protocol Version 4-- manually configure the IP address (automatically obtain IP address, DHCP server is required)
- Win + r type cmd to open a command prompt and type ipconfig / all view the local IP address
- DNS: Domain Name Resolution Protocol (domain names into IP addresses) is mainly used to access web pages
IP alternate configuration: Priority use DHCP, when the problems start standby configuration - Test network connectivity (to two hosts on the same network, or directly recruit two networks is Unicom)
Win + R & lt cmd command of ping (ICMP protocol)
(firewall settings)
self-test network tcp / ip driving ping 127.0.0.0 or its own IP address loopback address
Third, the configuration working group network
working group: equality, decentralized management, there is no network environment centrally managed
default workgroup: workgroup
computer name: unique in the same network
workgroup name: change to the same name in the same network, the working group agreed to surrender to
the domain network: standing division, with a controller, centrally managed network environment
Fourth, the Internet access
network service provider vendors (ISP): telecommunications; mobile; China Unicom
service providers temporary IP address, dns server address
network mode:
1 fiber optic - light cat --- router - computer (terminal)
2 to create a dial-up dial-pppoe

A: 1-127.0.0.0 subnet mask 255.0.0.0
B: 128-191.0.0.0 Subnet Mask: 255.255.0.0
C: subnet mask 192-233.0.0.0 : 255.255.255.0
2. What is the role of private address, which belongs to the private address
role: for internal business or personal home use for free, do not apply to the Corporation for assigned remission shortage of IP addresses
a: 10.0.0.1-10.255.255.254 / . 8
B: 172.16.0.1-172.31.255.254 / 16
C: 192.168.0.1-192.168.255.254 / 24
. 3 subnet mask, default gateway are acting
Subnet Mask: a network of bits of the IP address and host bits, to confirm whether the IP address belongs to the same network, when a computer's IP address to access the other is to decide whether you need to find a network gateway bit comparison between this unit and the target host
default gateway: the gateway for communication with a host of different networks , equivalent to as portals, typically a router
