ReNumber ip address via script ?

Hello,
I need to change ip address of many router can I do this with script ? for example 172.16.57.2/24 but only .57. will change with .58. at ip>>address and at routing>> Ospf >>Network.
if possible I will add script to all boards and do schedule to make all board same time.

Thnx
