I am not as close to the network as I used to be but I have not seen articles about the network apocalypse due to IPv4 address depletion. Unlike in the late 90’s when predictions of apocalypse were everywhere.
What happened?
Two things:
Network address translation (NAT) was introduced to allow organizations to use private addresses on their internal network and minimize the requirement for “real” IP4 addresses.
Second, IPv6 was created and introduced to expand the number of addresses available.
So, a direct answer is use IPv6 and/or NAT for internal networks.
