The protocol family used in the current global Internet is the TCP/IP protocol family. IP is the protocol
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
Redhat 5 disables IPv6 and redhat5 disables ipv6Redhat 5 Disable IPv6
IPv6 has not been fully popularized yet, but IPv6 is effective after the system is installed, which affects network performance to a certain extent. Therefore, we recommend that you disable IPv6. Now we wi

Collection rejected for iOS IPv6 compatibility support and IPv6 audit, iosipv6
Recently, I encountered a major challenge: IPv6 approval was rejected, so I searched for a solution to collect some documents that can be used for backup. We also hope that our peers can use it.Official documentation: Supporting IPv6 DNS64/
Recently encountered a big pit: IPV6 Audit was refused the problem, so wide-find solutions, first some can be used to collect data documents to spare. Also hope that colleagues can help.Official Document Description: Supporting IPV6 Dns64/nat64 NetworksOfficial development guidelines for IPV6-supported networksios-test Ipv6
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
H3CSE route-IPv6 Neighbor Discovery, H3CSE route-IPv6 neighbor
The ND (Neighbor Discovery, Neighbor Discovery) protocol is a key protocol of IPv6. It integrates some protocols in IPv4, such as ARP, ICMP Router Discovery, and ICMP redirection, and made improvements to them. This chapter describes important functions of IPv
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-

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,
