Apple's new policy is already known Www.cocoachina.com/apple/20160505/16124.html What we are most concerned about, then, is what we need to do as developers of apps. What is ipv6-only In the past, everyone was using IPv4, that is, the address looks like a 114.255.40.66. However, such an address is not enough, there is a similar IP address such as 2001:DA8:215:4009:250:56FF:FE97:40C7. At present, a network card will use both addresses at the same time,
From IPV6 details Ipv6 addresses can be divided into three categories: unicast addresses, wildcard addresses, and multicast addresses (many introductions on the following two types of networks) Unicast addresses can also be divided into global unicast addresses, local unicast links, and local unicast sites. See the IPV6 Address Allocation Table: This allocation
Many websites, such as Google, are both IPv4 and IPv6 Dual-line access. www.google.com resolution corresponds to many IP addresses, both IPv4 and IPv6. By default, the DNS server returns multiple IP addresses, while the local machine automatically selects the host based on the response speed of each address. Generally, people will modify the hosts file in the system directory and specify the Google addre
addresses: ◆ Uncertain address The Unicast address 0: 0: 0: 0: 0: 0: 0: 0: 0 is an uncertain address. It cannot be assigned to any node. One of its application examples is that when initializing a host, you can put an uncertain address in the source address field of any IPv6 Protocol address sent by the host before it obtains its own address. Uncertain addresses cannot be used as destination addresses in IPv6
The exact number of addresses contained in the 128-bit address space is 340,282,366,920,938,463,463,374,607,431,768,211,456. These spaces are sufficient to provide an independent IP address for each grain of sand on the earth. At the same time, IPv6 can automatically configure different types of addresses for host interfaces: Global Address (Globally) Global unicast address (unicast) Region address (on-site) Link local address) Local address) Broadcas
I also installed IPv6, which is not fashionable, but because some schools have started IPv6 experimental video sites to watch some IPv6 network TV programs, so I installed it too.IPv6 has the following advantages: 1. larger, the address protocol is increased from the power 32 of 2 to the power 128 of 2. 2. Faster, the next-generation Internet will be more than 10
Three virtual machines are installed on a 2G memory desktop and run well, that is, swap is used more often. See the previous article. Now the platform is basically ready, with its own laptop as the general control, and four machines running on the lab desktop (one solid and three virtual machines), coupled with one server, can do a lot of things, because KVM is a bridge network, the three virtual networks are consistent with the real-world status. They all contain their own IPv4 and
1. First verify that your DNS server supports IPV6, which generally refers to routes in the network.2. If there is no route in the network, add the IPV6 address and name of the other party directly in the hosts file.3. Using a UNC path, change the colon to a hyphen and attach the. Ipv6-literal.net to replace the symbol% with S. Example: \\2001-db8--85b-3c51-f5ff-
(IPv6/IPng: Internet Protocol version 6) Internet Protocol version 6th (IPv6) is the latest version based on IPv4. IPv4 is a network layer protocol that contains addressing information and some control information to Route packets in the network. There are two versions of the IP protocol: IPv4 and IPv6. IPv6
more specific requirements with little impact on common packets and special packet paths; stream tagging provides a mechanism for handling packet flow more efficiently, which is especially useful for real-time applications , authentication and confidentiality improvements make IPV6 more applicable to commercial applications that require special treatment of sensitive information and resources. 1.

1. Background knowledge With the continuous development of personal computers, mobile terminals and even the internet of things, there is a great demand for IP addresses. As the IPV4 protocol was designed without expecting that the network would be so developed in the future, the number of IP in the IPV4 network seemed to be stretched relative to today's demand. Add IPV4 Address resource allocation is uneven, resulting in some countries IP address resources are very tense, will suppress the deve
1. IPv6 knowledge abstract IPv6 addresses are all 128 bits in length. Each 16 bits is a dual-byte, which is represented in decimal format from 0 to 65535. 2. IPv6 address classification and Representation Method IPv6 is divided into unicast addresses (unicast), anycast, and
Depending on the deployment speed of the existing IPV4 address, the remaining address will be exhausted in 10-20 years. Therefore, the network gradually from IPV4 to IPv6 conversion is inevitable, the corresponding various network applications will support IPV6. For Java, starting from its 1.4 version of the IPV6 to provide better support, the programmer has basi

Since early May Apple has expressly stated that all developers submitting a new version after June 1 will need to support Ipv6-only's network, and everyone is starting to look at how to support IPV6 and which modules in the application do not currently support IPV6.
