If you need support from Yola please contact us via firstname.lastname@example.org or make use of our live chat service! We are working on a new approach to community-based support and during this transition period we are not adding any new threads to this forum. Many thanks to everyone who has participated over the years and we look forward to unveiling a new peer-to-peer support system soon!
It is indeed true that the world is running out of free IPv4 address space, and that more people are going to need to transition, either to NAT'd space (thus freeing up more IPv4 address space), or to IPv6 networks.
However, I wouldn't worry too much about what the doomsaying journalists write - mostly they're just looking for a good story. For example, when they say "only 6% of IPv4 address space is free", they're not mentioning two important facts: firstly, that is still over a quarter of a billion addresses available; and secondly, that doesn't count addresses that are allocated to providers, but not actually being used by anybody.
These latter addresses form a large part of the IPv4 address space, and can be given out to people who want to use them at a later date - they are often temporary, and get reused, thus making sure that the pool doesn't run out too fast.
Having said all that, you don't need to worry from a Yola perspective: we already have a pool of IP addresses available, and we use virtual hosts to put vast numbers of sites on the same IP, thus reusing addresses and making sure that we're not going to run out.
In other words: don't worry, we've got you covered!
