Windows Server 2016 network services (i)

Network Fundamentals

• IPv4 Network

• TCP4 Layer

• 
  

• IP Address: V4 version: + Binary number, each 8 a set of bits representing the identity of each computer in the network

• 192.168.1.1 192.168.2.1

• Divided into network bit and host bit, same network bit, different host bit can communicate

• according to IP different use environments define the 5 Kind of network

• divided into public IP and Private IP

• special ip : 169 start - auto private ip address ( ip address conflict and cannot get ip address)

• 127.0.0.1- Local loopback -localhost

• Subnet Mask: + Binary digits, each 8 a group of bits, from left to right, with the same continuous 0&1 composition

• 192.168.1.100/30 192.168.1.1/24

• 255.255.255.252 255.255.255.0

• 11000000.10101000.00000001.01100100

• 11111111.11111111.11111111.11111100

• 11000000.10101000.00000001.01100100

• 192.168.1.100

• 11000000.10101000.00000001.00000001

• 11111111.11111111.11111111.00000000

• 11000000.10101000.00000001.00000000

• 192.168.1.0

• through subnets and IP make " with the " The result of the operation defines the IP belong to the network segment, the same network segment IP can communicate

• you can define subnets to help configure IP address to achieve more network & Host = Sub-network Division

• display mode: 255.255.255.0&/24

• Gateways ( GW )

• two different networks IP address when communication is required

• can be used with IP address forwarding device (Router & switch), the device is configured and the network that is currently connected wants to match the IP Address

• on computers of different networks, will be able to forward ip The address device's and current computer's ip ip " Gateway "

• When the local computer sends data to a different network, the data is first sent to " Gateway " in the information IP Address

• 
  

• DNS : Domain Name resolution

• Client First DNS the server submits the domain name that needs to be resolved DNS returns information about the domain name submitted by the client ( IP address)

• Order of client Domain name resolution: Local cache: ipconfig /displaydns

• /flushdns

• Local Hosts file

• 
  

• in the network adapter settings DNS Server's IP Address

• Get-dnsclientserveraddress

• nslookup through the local computer's dns IP for ' Microsoft Yahei '; font-size:32px ' address, go to query dns information in the server

• Set Type=a , TXT , MX Record Type

Set IP Address: get-netipaddress

• Set-netipaddress

common use tool: ipconfig ping tracert telnet

• Network Information analysis Tools Microsoft Message Analyzer(protocol, message)

IPv6 :

• huge address pool: 2001 : DB8 : 0 : 2d4c :1CC:DD : 1122:1234           recommended by dhcp assign

• IPv6 security: Requires end-to-end encryption

• Typical IPv6 Address: FE80 Start =169 Local private address at the beginning

• :: 1=127.0.0.1

• configuration: Some important servers ( DC , Mail) in no IPv6 in a network environment, disable IPv6 Protocol
