How does one server provide DHCP service for two different network segments?

How does one server provide DHCP service for two different network segments? -- Linux general technology-Linux technology and application information. For details, refer to the following section. Background: I have a DELL 1750 server with dual-gigabit NICs. The company's network environment is: Intranet and Internet physical isolation. That is, the Intranet is 10. 98. *. * and the Internet is 192. 168. In the past, two DHCP servers provided DHCP services for the two network segments respectively. In addition, each CIDR block is divided into many small CIDR blocks corresponding to each department. For example: 10. 98. *. * network segment, which is also divided into 10.98.140. *. 10.98.155.*10.98.151. * and so on. The 192. 168. *. * network segment is also divided into 192.168.16. *, 192.168.32. *, 192.168.19. *, and so on.
Q: Can I assign two network adapters of the server to the IP addresses of two network segments and then provide DHCP services for the two network segments? If yes, the question that follows is: how to write the/etc/dhcpd. conf file? Paste all the configurations of the previous two machines into it? I think it is unlikely. If they are all put in a configuration file, how do two NICs distinguish which configuration corresponds to it?
Thank you!
