For example this Russian IT consulting company says:
We provide full visa and relocation assistance for you and your family. We will help you to relocate to Krakow with support for booking flights, accommodations and moving services! We offer a full relocation allowance package that includes initial accommodation expenses, real estate agency services, and compensation for tickets to Krakow.
So as people have mentioned above, if you are experienced IT specialist, then most international companies advertises some kind relocation package. You can read about it on their websites or in job offers. While if you apply to smaller company you may get nothing without asking.
