Are you aware that IPv4 allocations will be depleted in less than two weeks with the RIR's? This means no new allocations will be given out to companies. The remaining 7 /8 netblocks will be distributed to the RIR's 1 each and have very strict rules for allocation.
Why would this effect you? Simple
- "SEO Hosting" will become a lot more expensive and or gone completely.
- Hosting in general will go up in price due to supply/demand of IPv4 Space
- People who utilize bulk IP space is going to go up dramatically in prices and/or shutdown
- Software will break with IPv6 unless it can already handle it, i.e traffic scripts etc anything that logs IPs deals with IP addresses.
Is your current host utilizing IPv6 and running it in a dual stacked environment? You should be getting a IPv4 and a IPv6 IP with every machine/request/setup that you do. IPv6 is not hard and can run in parallel with IPv4 so why not start utilizing it?
At first people wont care or really matter, in probably 2 years reality will strike with everyone because their net blocks they have in reserve will be depleted and then panic will set in. Most hosting companies these days run dual stacked environments and are setup to handle IPv6 the problem really lands on end user ISP's who are just god awful slow at adapting. Comcast to my knowledge is the only ISP thats testing IPv6 so atleast they are one up on most networks. While yes there are ways at recooping IP space from say China who happens to be one of the biggest hogs for IP space but this just buys time before it has to happen.
Some people are calling IPv6 the newn y2k "bug" but this is nothing like the "y2k" problem. IPv4 is running out and will soon be gone. Its time to adapt and move forward. People on NANOG have been talkinga bout a IPv4 blackout date, in other words the day most networks should be fully switched over to IPv6 and the date was suggest for December 31st 2019. Yes its 8 years away but a LOT can happen in 8 years. This is real people so wake up, start poking your hosts and software companies to see if they support IPv6 yet, if not bug them until they do. Would you rather be one of the few/first sites online when google starts seeing native IPv6 on its searches and indexes you on IPv6 when there is little competition? or be stuck in a sandbox with everyone else.
