Cum setez IP static la calculator

03/10/2018

Each computer in a network has its own internal IP address. That IP address may be static, which means that it never changes. Or, as is likely if you share an Internet connection with other computers, the internal IP address may be assigned dynamically and may change from time to time. 

Note: in a network configuration, the internal IP is not the same as the IP assigned by your ISP. The IP assigned by your ISP can be either static or dynamic. 

When you are opening ports to allow incoming connections to your computer, your computer must be assigned a static internal IP address, to ensure that the incoming connections always go to the correct computer. 

There are several steps:

  1. See your current IP address
  2. Choose a static IP address
  3. Assign the static IP address

Current IP Address

Find your current IP address and whether it is static or dynamic:

  1. Open Windows Start menu.
  2. Select Run. Type: command and click OK.
  3. At the blinking cursor, type: ipconfig /all and press Enter.
  4. Look for these entries near the end of the list:- Dhcp Enabled. No means your IP address is static. Yes means it is dynamic.- IP Address. This is your current IP address.
  5. To exit, at the blinking cursor, type: exit and press Enter.

If your current IP address is:

  • Static, then make note of the IP address. You need the IP address when you open ports in your router or firewall.

  • Dynamic, then assign a static IP address instead.

Choose an IP address

Choose an IP address, and collect other information needed in order to assign a static IP address to your computer.

  1. In your router administration program, find and remember this information: 

    • Router (Gateway) IP address
    • Subnet Mask
    • IP addresses of your DNS servers
  2. In your router administration program, find an IP address that can be assigned as a static IP. The address: 

    • Must not be one that might be assigned to someone as a dynamic address.
    • Must not be one that has been assigned to another device (often these are the low numbers).
    • Must be lower than the range of dynamic addresses.
