The reason we can only create 4094 VLANs on one physical network is due to the limitations of the VLAN tagging protocol. VLANs are created by assigning a unique VLAN ID to each virtual network. In the VLAN tagging protocol, the VLAN ID is represented by a 12-bit field in the Ethernet frame header. This means that there are only 4096 possible VLAN IDs (2^12 = 4096).

However, two VLAN IDs are reserved for special purposes. VLAN ID 0 is reserved for the default VLAN, which is used for untagged traffic on a port. VLAN ID 4095 is reserved for the reserved VLAN, which is used for control traffic and cannot be configured as a regular VLAN.

Therefore, out of the 4096 possible VLAN IDs, we can only use 4094 for creating VLANs on a physical network. This limitation is inherent to the VLAN tagging protocol and cannot be exceeded.
