If for any reason you have changed or configured the IP adress incorrectly it is likely that don’t have internet access from your computer. To solve this problem it will be necessary to enable the protocol DHCP.
The first thing you should know is what DHCP is and how it affects your Internet connection. In addition, you will have to know in which OSI layer it acts to better interpret its work.
To resolve all these doubts, it will be convenient for you to read this article to the end. Too we are going to explain the step by step you must do to enable the DHCP protocol in Windows 7.
What is DHCP and how does it affect my Internet connection?
DHCP is a protocol used to configure IP addresses dynamically. In this way, the devices that are in a network (to which a specific IP is assigned) can communicate with other networks through a list of IP addresses used by the server. Dynamic Host Configuration Protocol.
The work that this guy does client-serverSince DHCP acts as a server, organizing the IPs, and the devices that require an IP address to connect to a network are the clients of this protocol.
As IPs become free, DHCP reassigns them by configuring the parameters automatically, dynamically or manually. This protocol can be used both in IPv4 as for IPv6, on wired and wireless networks. DHCP is in charge of keeping the Internet connection stable between all the devices that make up the network. But it has a great vulnerability and it is the ease of being manipulated by unauthorized people.
At what network layer and how does the dynamic host configuration protocol work?
He Dynamic Host Configuration Protocol works in the seventh layer of the OSI model and in the TCP stack DHCP appears in the fourth. This is because users can access their services to exchange information through programs. Its job is to manage a list of IP addresses that it has among the components of a network, this is done so that clients, or nodes, can communicate with other IP networks.
In this way the DHCP configure shape automatic addresses to devices through special hardware (routers and hubs). To assign IP addresses, it is done through the client-server model. The client communicates with all the members of the network to find out which DHCP server is available for their requestThis makes all the servers listen to this request and consult their database for a free IP so that it can be related to the MAC address of the requesting computer.
He DHCP it uses the database it has to configure the following parameters: the IP, name and address of the domain name system server (DNS), waiting for the web address resolution protocol, the subnet mask, the gateway, the SMTP and proxy settings. Once these parameters are set, the server database is saved DHCP the MAC with the IP delivered automatically. Assignment can also be done dynamically or manually.
Learn step by step how to enable DHCP protocol in Windows 7
To enable the DHCP protocol on your Windows 7 computer, you must do this step by step:
- Open the Control Panel from the start menu of Windows.
- Go to Network and Internet and search Center network and sharing.
- Find the tool Network connections and right click on it.
- Select function Properties.
- Click on TCP / IP protocol.
- Search Properties and select this function.
- Go to the tab general.
- Click on Network functions.
- Tap on Obtain an IP address automatically.
- Click on To accept.
