When a computer boots, it can get its network information through:

When a computer boots, it can obtain its network information through the DHCP (Dynamic Host Configuration Protocol).

DHCP is a network protocol that automatically assigns IP addresses, subnet masks, default gateways, and other network configuration settings to devices on a network. When a computer boots and connects to a network, it can send a DHCP request to a DHCP server. The DHCP server then provides the necessary network information to the computer, allowing it to join the network and communicate with other devices.

DNS (Domain Name System) is responsible for translating domain names into IP addresses and is not directly involved in providing network configuration information during booting.

SMTP (Simple Mail Transfer Protocol) is used for sending email messages and is not related to obtaining network information during booting.

LDAP (Lightweight Directory Access Protocol) is a protocol used for accessing and managing directory information, typically for user authentication and directory services. It is not specifically used for obtaining network information during the boot process.

X11 is a network protocol used for graphical user interfaces, specifically for remote display and control of graphical applications. It is not involved in obtaining network information during booting.
