, the following address: fe80:cd00:0000:0cde:1257:0000:211e:729c can be abbreviated as fe80:cd00:0:cde:1257:0:211e:729c 4, can omit the continuous 0 If the characters of consecutive multiple bit groups are all 0, you can omit all 0, for example, the following address: fe80:cd00:0000:0000:0000:0000:211e:729c In addition to the method introduced in the 3rd, the abb

traffic into the tunnel and transmit it to the ISATAP router to traverse the entire IPv4 network.1) Now we configure the ISATAP router. The IPv4 address assigned to the router is 2.2.2.2/24, and a tunnel interface is created for ISATAP, in this case, the tunnel interface generates an interface ID of 64bits Based on the IPv4 address. The link local address of the tunnel interface is: fe80: 0000: 5efe: 202: 202. In addition, you also need to configure

forwarding, the IP packet changes the checksum (checksum) and TTL (each time a router passes through a TTL value minus one) Ipv6 only changes to TTL without checksum The CPU does not support 128-bit forwarding. It is best to only 64-bit. · Theoretical limit: 4.3 billion (billion) 4.3 billion Practical limit: 250 million (million) 0.25 billion Over 420 million Internet in Y2001 (Less than 10% of the worldwide population) No broadcast. multicast r

compression can only is applied once in an IP address.To determine how many blocks has been omitted, you just has to count the remaining blocks and subtract this number from 8.EXAMPLE:FE80:0:0:0:2AA:FF:FE9A:4CA2 can is zero compressed to FE80::2AA:FF:FE9A:4CA2.There are only 5 sets of data, with a double colon in the middle indicating a compressed 0,8-5=3; 3 groups of 0000 are compressed.IPV6 PrefixIPV6 prefixes is used to express

why ... The following is only a detailed description of how the Teredo Tunneling protocol is used on Win7. 2.3.1 confirm that the operating system has the IPV6 protocol installed Use the Ipconfig/all command to see if the system has the IPV6 protocol installed. Windows Vista and Windows 7, 2008 already have the IPV6 protocol installed by default and do not need

ipv6 information is added to the conf file. writing to the/sys/module/ipv6/parameters/disable_ipv6 file cannot control the IPv6 protocol. We recommend that you use variable control in the proc directory. Method 3: The following directory is available under the/proc/sys/net/ipv6/conf/directory: [Root @ root conf] # ls

, and then parse the ifconfig result string to get the ip address of en0 (Wifi), pdp_ip0 (mobile network). Note: (1) IPV6 unicast address starting with FE80 will affect our judgment on both the emulator and the real machine, so special processing is performed here (when the first time encounters an IP address that is not a unicast address, it is the local machine. IP address). (2) In the

". (Remote connection may interrupt the network. We recommend that you perform the above operations on site) C. Check whether IPV6 has taken effect.After the IPV6 protocol is enabled, if it is accessed from a pure ipv6 network environment or an ipv4/ipv6 Dual-stack environment, and the address is automatically obtaine

What are the differences between IPv4 and IPv6? We can understand the difference between IPv4 and IPv6 through the following, we will appear IPv4 and IPv6 when we connect the wireless network, then where is the difference between the two? Want to know friend please see below. Most of us use the second-generation Internet IPV4 technology, its biggest problem is t

module Compared with Windows systems, Linux provides better Ipv6 support. generally, Ipv6 can be used directly in Linux versions based on the 2.4 Kernel. before using IPv6, it depends on whether the system Ipv6 module is loaded, if you do not have one, you can use the command to manually load the file. This requires t

, these zeros can be abbreviated as 0. For example, the following address: FE80: CD00: 0000: 0CDE: 1257: 0000: 211E: 729C Can be abbreviated FE80: CD00: 0: CDN: 1257: 0: 211E: 729C 4. Consecutive 0 values can be omitted. If all the characters in multiple consecutive single-digit groups are 0, all 0 values can be omitted. For example, the following address: FE80:

, these zeros can be abbreviated as 0. For example, the following address: Fe80: cd00: 0000: 0cde: 1257: 0000: 211e: 729c Can be abbreviated Fe80: cd00: 0: CDN: 1257: 0: 211e: 729c 4. Consecutive 0 values can be omitted. If all the characters in multiple consecutive single-digit groups are 0, all 0 values can be omitted. For example, the following address: Fe80:
