Require some advise on proxies

Alright guys I'm completely new to proxies and just gonna try to implement some pintrest automation in my marketing strategy and i would like to clarify some things regarding proxies. Can i host multiple IPs on a VPS and where do I lease/buy the IPs? Can i use any IP or are there any other considerations that I need to take note of?

Yes, you can configure multiple IPs on a VPS, you may use multiple browser instances to configure each proxy IP. Also, for any account management it is ideal if you use private/dedicated IPs.

You can create your own IPS or You can Buy IPs from the marketplace.
To manage bulk amount of accounts I would suggest using Jarvee - Currently the best automation tool out there.

If you’re new just go ahead to the marketplace to get yourself some proxies. You can use multiple of them on one pc.
