Since ipv4 belongs to one of the osi model layers, what happens with ipv6? Does it also belong to the OSI model?

Yes, both IPv4 and IPv6 operate at the same layer of the OSI Model (Open Systems Interconnection). Both are Network Layer protocols (the third layer) in this model.

The main function of the Network Layer is to provide direction and routing of data (in the form of packets) across different networks to ensure that it reaches its correct destination.

The main difference between IPv4 and IPv6 lies in their structure and how they handle addressing information. IPv6 was developed to address the shortage of IP addresses available in IPv4, introducing 128-bit addresses instead of the 32-bit addresses used by IPv4.

This allows for a virtually unlimited number of unique addresses, along with improvements in areas such as address allocation, security with IPSec (which is mandatory in IPv6), and routing efficiency.

However, in terms of their place in the OSI Model, both protocols function in the same way, facilitating communication over networks by addressing and routing packets.

The OSI Model is a conceptual framework that divides network functions into seven distinct layers, from physical (layer 1) to application (layer 7), with both IPv4 and IPv6 being at the layer that ensures data reaches from point A to point B through potentially complex and changing networks.
