In Windows 7 above system, when setting the local IP address often see colleague contains IPV4 agreement item and IPV6 Agreement item, Inquire IPV6 and IPv4 difference, the following small series for everybody introduced under IPV6
to the sustainable development of the Internet and long-term. At present, the Internet organization has decided to set up two specialized working groups to develop corresponding international standards.
IPv6 FAQ
1. What is IP? What is
What is the difference between IPv4 and IPv6 service quality?This is an interesting question that people often ask. The two versions of the Protocol have no difference in terms of servi
The first one does not say Ha, 32bit directly upgraded to 128bit.
From 2 to 32 to 2 of 128 times, every grain of sand on earth can be divided into one IP address. This is the most windy place in IPv6.
In IPV6, routers cannot configure interfaces using automatic configuration mechanisms and must be manually configured.
So, my understanding
We all know the essential differences between IPv6 and IPv4 protocol networks. So what are the differences between the two in the two-way session communication process? The following describes the content in detail. The NAT-PT can only be used for applications that initiate a session by a terminal in the Ipv6 network,
In fact, here IPv6 ACL (access-list) and IPv4 are very similar, all as a practice to verify the principle of it.
1, about the standard access list.
Configuration is the case, and IPv4 is not much different, the difference
The protocol family used in the current global Internet is the TCP/IP protocol family. IP is the protocol of Network layer in TCP/IP protocol family, and it is the core protocol of TCP/IP protocol family. The current version number of the IP protocol is 4 (referred to as IPV4
, nor can it occur overnight. The transition takes time and cost. However, in the long run, IPv6 is conducive to the sustained and long-term development of the Internet. At present, Internet organizations have decided to set up two specialized working groups to develop corresponding international standards.
What are the features and advantages of
summed up the following points:
First, the ability to extend routing and addressing
IPV6 the IP address from 32 to 128 bits to support a larger address space, estimating that there are 4*10^18 IPv6 addresses per square metre on the surface of the Earth, so that IP addresses will not run out in the foreseeable future.
The IPV6 address
IPv6 is often compared to a small island, and IPv4 is compared to the ocean. In fact, we will also use different methods and technologies to complete the transition from IPv4 to IPv6. The real islands and oceans do not exist, beca
China is developing industry standards for the technical requirements for dual-stack firewalls, the first technical standard for firewall devices in the transition from IPv4 to IPv6 in China. The standards led by China Mobile and drafted by Huawei are still being formulated and are expected to be completed by 2013.
The IPv4
Public Static String Getlocalip (){ Try { String Hostname = DNS. gethostname (); // Get the Host Name Iphostentry ipentry = DNS. gethostentry (hostname ); For ( Int I = 0 ; I { // Select an IPv4 IP address from the IP address list. // Addressfamily.

Internetwork indicates that the IP address is IPv4,// Addressfamily. internetworkv6 indicates that the address
IPV6 is the abbreviation for Internet Protocol Version 6, where Internet Protocol is translated as "Internet Protocol". IPV6 is the next generation IP protocol designed to replace the current version of the IP Protocol (IPV4) by t
In network protocols, IPv6 is the most important thing. The IPv6 network protocol will replace the new version of V4. Our merchants and users share a common expectation for this agreement, but the use of this network is not widely used at present. Next, let's talk about this.
1. IP
No matter whether enterprise users are ready or not, IPv6 network deployment is just around the corner. The demand for advanced site selection technology is growing, and everything in life will be able to use this technology.
At the same time, VoIP has become the mainstream technology and has become the basis of other network services. It
, Internet Key Exchange) are also complex, if you want to do this yourself. This is one of the main functions provided by IPsec and VPN. Of course, IPsec can be very powerful, but in some cases remote access is very fragile, for example, using a mobile device to access an enterprise network. The provision of such services by the IT Department will further increase the management burden.
There
services by the IT Department will further increase the management burden.There is no need to take a big step to complete the transition from the current IPv4 network to the IPv6 network, because the new technology provides the gateway service between the two networks, for example, the BIG-IP IPv6 gateway produced by
