Who assigns my ip? [closed]

It is always the DHCP server. The point is that as the internet is a network, there are several layers that can change this. For example. if your pc is connected directly to the modem, your ISP's DHCP will give you your IP, if there is a router in the middle (and this is also true for those who are also modems) then the router has a small DHCP server and it will create another internal network and give you an IP of that network (and for the internet, all the PC's of that subnet have the same IP).

Providers usually provide dynamic IP addresses for residential customers, meaning your IP changes over time on the internet, but you can usually request static IP as an extra service from your provider, and of course, for a price.

Request IP

  

Who says my computer has an ip, is it the internet provider or Dhcp?

When you hire a provider, it defines an IP for your router, this IP can be dynamic or static.
