sudo ifconfig eth0 100.100.100.60 netmask 255.255.255.0
Note: 100.100.100.60 is the ip address you want to change (ie the destination address) followed by the subnet mask
Another way: modify the file /etc/network/interfaces
If you want to turn off the DHCP server (note: turn off your own dynamic routing configuration, not the server's DHCP to other clients), you only need to modify the file sudo vim /etc/network/interfaces
Add the following statement:
auto eth0
iface eth0inet static
addressxxx.xxx.xxx.xxx #IP address
netmaskxxx.xxx.xxx.xxx #Subnet mask
gatewayxxx.xxx.xxx.xxx #Gateway

UbuntuServer modify DNS
Open /etc/resolv.conf
sudo vim/etc/resolv.conf
Change it to the following:
searchlocaldomain #If this Server is a DNS server, you can add this sentence, if not, you can leave it out
nameserver172.16.3.4 #DNS you want to modify
nameserver172.16.3.3 #DNS you want to modify

UbuntuServer The last step, and the most important step
Add this command to restart the network configuration in rc.local:
sudo/etc/init.d/networking restart
Note: If you are using a remote connection tool such as XShell, the above modification is unsuccessful except for the first one (that is, you can modify the ip at the top)
