Want to change the Service Console IP address from the command line real quick like?
esxcfg-vswif -i [new IP] -n [netmask] [vswif]
example (as root)
esxcfg-vswif -i 172.25.100.92 -n 255.255.255.0 vswif0
Q: How do I know what is my vswif?
A: esxcfg-vswif -l

you can also use esxcfg-vswif -l to verify the ip of your service console.
