There's an ongoing "panic" all over the news for some time now about IPv4 running out and IPv6 being the savior. All the big companies are preparing and showing how it should be done (last actions from Google, FaceBook). I do understand the problem and I do think people should slowly starting to move but is it also a big deal for small companies?
I've clients which are usually very small companies with 5 to 50 employees using Windows XP/Windows 7 for their clients and Windows 2003/Windows 2008R2 for their servers. Nothing complicated with 1 up to 5 switches (some managed and some unmanaged but nothing too complicated - Linksys/D-Link). On top of it there's usually modem provided by ISP and small
home router (D-Link, Draytek, Linksys) or if the client is a bit bigger something like FortiGate FW50B.
How should they prepare? Is there anything each company should do? Like buy new routers? I'm looking for general advice on how to approach this from my clients perspective. Should we wait for ISP to come to us first and then try to fix things later or there's nothing we should be worried about and just do what we do and there's nothing to be done ?
