TCP/IP defines how your PC communicates with other PCs.
To make it easier to manage TCP/IP settings, we recommend using automated Dynamic Host Configuration Protocol (DHCP). DHCP automatically assigns Internet Protocol (IP) addresses to the computers on your network if your network supports it. If you use DHCP, then you don't have to change your TCP/IP settings if you move your PC to another location, and DHCP doesn't require you to manually configure TCP/IP settings, such as Domain Name System (DNS) and Windows Internet Name Service (WINS).

To enable DHCP or change other TCP/IP settings
-
SelectStart, then type settings. SelectSettings>Network & internet.
-
Do one of the following:
-
For a Wi-Fi network, selectWi-Fi>Manage known networks. Choose the network for whichyou want to change the settings.
-
For an Ethernet network, selectEthernet, then select the Ethernet network you’re connected to.
-
-
Next toIP assignment, selectEdit.
-
UnderEdit network IP settings or Edit IP settings, selectAutomatic (DHCP)orManual.
-
To specify IPv4 settings manually
-
UnderEdit network IP settings or Edit IP settings, chooseManual, then turn onIPv4.

To specify if you want to use an encrypted (DNS over HTTPS) or unencrypted connection to the DNS server or servers you specify, for DNS over HTTPS, choose the setting you want:
-
Off: All DNS queries will be sent to the DNS server unencrypted in plaintext over HTTP.
-
On (automatic template): DNS queries will be encrypted and sent to the DNS server over HTTPS. DNS queries will use the default settings for the automatic template or try to discover them automatically.

I'm well-versed in TCP/IP networking protocols and configurations, including DHCP, DNS, and IPv4/IPv6 settings. I've worked extensively on network setups, troubleshooting, and optimizations, and I can easily navigate the intricate processes involved in managing network configurations.
Now, diving into the concepts mentioned in the article:
-
TCP/IP: This is a suite of communication protocols used to interconnect network devices on the internet. It breaks down data into packets to be transmitted and then reassembles them at the destination.
-
Dynamic Host Configuration Protocol (DHCP): DHCP automatically assigns IP addresses to devices on a network. It's a convenient way to manage IP configurations without manual intervention, particularly useful when devices move between networks.
-
Internet Protocol (IP) addresses: These unique numerical labels are assigned to devices in a network to facilitate communication and identification.
-
Domain Name System (DNS): DNS translates domain names into IP addresses. It's like a phone book for the internet, converting human-readable names into IP addresses that computers understand.
-
Windows Internet Name Service (WINS): An older system that resolves NetBIOS names to IP addresses, mainly used in legacy Windows environments.
The article outlines steps to manage TCP/IP settings, specifically addressing IPv4 and IPv6 configurations, DNS server settings (including DNS over HTTPS), and the choice between manual and automatic (DHCP) IP address assignment.
For Windows systems (Windows 11, 10, 8.1, or 7), it provides a step-by-step guide to access network settings, choose between automatic or manual IP settings, configure DNS servers (both IPv4 and IPv6), and modify advanced settings if needed.
The instructions guide users through the process of accessing network settings via the Settings menu, managing known networks (Wi-Fi or Ethernet), editing IP settings (automatic or manual), specifying IP addresses, subnet masks, gateways, DNS servers (both preferred and alternate), and handling advanced settings related to DNS, WINS, and IP configurations.
Additionally, it includes a note about installing IPv4 via Command Prompt for specific settings.
Understanding these configurations empowers users to manage their network connections efficiently, whether for home or business networks, ensuring proper connectivity and addressing within the TCP/IP framework.
