How to check TCP IP settings on a Windows computer

January 31, 2017

Transmission Control Protocol/Internet Protocol (TCP/IP) is the basic communication language of the internet – it’s how computers speak to each other. Every computer that is connected to the internet must run a TCP/IP program. /

Typically, you won’t need to manually adjust your TCP/IP settings, because most devices use an automated Dynamic Host Configuration Protocol (DHCP). DHCP automatically assigns Internet Protocol (IP) addresses to the computers on your network. 

In the rare event that you need to manually adjust TCP/IP settings or enable DHCP, just follow these steps:

  1. Depending on your operating system, perform one of the following:
    • In Windows 10, in the search box on the taskbar, type View network connections, and then select View network connections at the top of the list.
    • In Windows 8.1, select the Start button, start typing View network connections, and then select View network connections in the list.
    • In Windows 7, open Network Connections by selecting the Start button, and then selecting Control Panel. In the search box, type adapter, and then, under Network and Sharing Center, select View network connections.
  2. Regardless of your operation system, the following instructions still apply. Right-click the connection that you want to change, and then select Properties. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
  3. Select the Networking tab. Under This connection uses the following items, select either Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6), and then select Properties.
  4. To specify IPv4 IP address settings, do one of the following:
    • To get IP settings automatically using DHCP, select Obtain an IP address automatically, and then select OK.
    • To specify an IP address, select Use the following IP address, and then, in the IP address, Subnet mask, and Default gateway boxes, type the IP address settings.
  5. To specify IPv6 IP address settings, do one of the following:
    • To get IP settings automatically using DHCP, select Obtain an IPv6 address automatically, and then select OK.
    • To specify an IP address, select Use the following IPv6 address, and then, in the IPv6 address, Subnet prefix length, and Default gateway boxes, type the IP address settings.
  6. To specify DNS server address settings, do one of the following:
    • To get a DNS server address automatically using DHCP, select Obtain DNS server address automatically, and then select OK.
    • To specify a DNS server address, select Use the following DNS server addresses, and then, in the Preferred DNS server and Alternate DNS server boxes, type the addresses of the primary and secondary DNS servers.
