Why do we need IPv6 IPv4 Exhaustion: Short-term solutions:
{"Image DocumentName": "Why do we need IPv6? IPv4 Exhaustion: Short-term solutions:", "Image ImageDescription": "IPv4 contains about 4 billion addresses. However, a large block is reserved for special use and not for public. Rapid Internet growth in the 1990s also dramatically used up IP addresses. Mobile devices, broadband connections all use IP now. Current IPv4 addresses are predicted to be exhausted by Short-term solutions: Network Address Translation (NAT) DHCP in broadband (xDSL, ETTx) applications. Use of classless subnet mask (CIDR) As of September 2008, Geoff Huston of APNIC predicts with detailed simulations an exhaustion of the unallocated IANA pool in February Tony Hain of Cisco Systems predicts the exhaustion date to be around November These predictions are derived from current trends, and do not take into account any last chance rush to acquire the last available addresses. But as everything is based on IP now, we need a long-term solution to address this problem. 8.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
