Is there *currently* a shortage of IPv4 addresses?

["Anne P. Mitchell, Esq." <amitchell () isipp com>]

I know that a shortage of IPv4 addresses has been anticipated for quite some time (literally decades), however, is 
there a shortage *right now*?

I ask, because Liquid Web is using it as an excuse to raise their prices:

"We're contacting you today to inform you of a change to your account. As you may know, the global shortage of IPv4 
addresses (https://www.ripe.net/manage-ips-and-asns/ipv4/ipv4-run-out) continues to impact web hosting companies around 
the world. ... Effective August 31st, we will be updating our per IPv4 address price to $2.00 per IP."
