<div dir="ltr" id="yui_3_16_0_1_1427846743016_14256">That was my point. Even if an ISP offers IPv6 to 100% of its customers, it still needs to offer IPv4 to practically 100% of its customers as well, because there's a lot of systems/software/tools out there that don't yet speak IPv6.</div><div dir="ltr" id="yui_3_16_0_1_1427846743016_14256"><br></div><div dir="ltr" id="yui_3_16_0_1_1427846743016_14256">/ So nobody here who is advocating deploying IPv6 is saying (or has said) to switch off IPv4 at the same time.</div><div dir="ltr" id="yui_3_16_0_1_1427846743016_14256"><br></div><div class="qtdSeparateBR"><br><br></div><div class="yiv3136499805yqt1019664819" id="yiv3136499805yqtfd39726"><br clear="none">
