Which OS? Usually you are doing it with netsh, but the syntax and default interface names depend on the OS. Example:
@echo off
REM values needing changes for each machine
set NIC=LAN
set IP=1.2.3.4

REM DHCP or static?
(
  netsh interface ip show addresses %NIC% | find "DHCP enabled" | find "No" >nul && (
    REM is static, switch to DHCP
    echo set address   name=%NIC% source=DHCP
    echo set dnsserver name=%NIC% source=DHCP
  ) || (
    REM is DHCP, switch to static
    echo set address   name=%NIC% source=static address=%IP%/24 gateway=1.2.3.1
    echo set dnsserver name=%NIC% source=static address=1.2.3.1
    echo add dnsserver name=%NIC%               address=1.2.3.2 index=2
  )
) | netsh interface ip

You can adapt the script (or use another one) for you to
- get the currently assigned IP address and subnetmask + gateway
- set the IP config to use a static config, re-using the former IP address, subnet mask and gateway.

I have some tools that can help with these goals...

Forgot to use the "context" parameter. Also note that there are language-dependent parts for detecting whether DHCP is used.
I assumed the subnet to be /24 (255.255.255.0), and used that as a fixed value.
@echo off
REM values needing changes for each machine
set NIC=LAN
set IP=1.2.3.4

REM DHCP or static?
(
  netsh interface ip show addresses %NIC% | find "DHCP enabled" | find "No" >nul && (
    >con echo static, switch to DHCP
    echo set address   name=%NIC% source=DHCP
    echo set dnsserver name=%NIC% source=DHCP
  ) || (
    >con echo DHCP, switch to static
    echo set address   name=%NIC% source=static address=%IP%/24 gateway=1.2.3.1
    echo set dnsserver name=%NIC% source=static address=1.2.3.1
    echo add dnsserver name=%NIC%               address=1.2.3.2 index=2
  )
) | netsh -c "interface ip" >nul
