With the rapid development of the Internet, modern people's lives are inseparable from the Internet. However, the old oneipv4The agreement is facingAddressSpace is limited to meet the growing demand for network equipment. To solve this problem,ipv6As the next generation of Internet protocols, it came into being. ipv6Compared toipv4And not only inAddressThe number has been improved, and it has been enhancedRoutingEfficiencyand security, more straightforward end-to-endCommunicationsIt was also possible. So, turn on broadbandipv6has become an individual user、Carriersand important national initiatives to provide users with more advanced and stable network services, and for:Internet of ThingsThe time has come to get ready.
1. More IP addresses
ipv6Almost unlimited IPs are offeredAddressEach device can have a unique global public networkAddress。In contrast, inipv4world, due toAddressshortage problem, people have to use nat (Network Address Translation) to solvePublic IP addressAddressNot enough cases. Whileipv6The emergence of NAT eliminates the need for NAT, and each device is able to have its own independent global public networkAddress, providing greater flexibility for network connectivity andScalability
2. Simplified network configuration
ipv6The device can be obtained through automatic configurationAddress, e.g. with slaac (statelessAddressauto-configuration) technology. Compared toipv4ipv6The network configuration process is simpler and more automated. This greatly reduces the burden of network configuration for users and improves network deploymentEfficiency
3. End-to-end connectivity
Since each device can have a unique global public networkAddressipv6True end-to-end connectivity is achieved. ipv6It makes it possible for the external network to directly access the intranet devices, reducing various connection problems caused by NAT. This is necessary for the needRemote accessScenarios of systems or devices are useful, such as home automation systems or remote monitoring cameras.
4. Security enhancements
ipv6Designed with security in mindipsecIt becameipv6standard components, and inipv4is only optional. ipsecis a group used to encrypt the InternetCommunicationsprotocol standards, which are able to provide higher network security and protect user privacy andData Security。Compared toipv4ipv6There are clear advantages in terms of security.
5. More efficient routing
ipv6Addresshierarchical and largerAddressSpace makesRoutingMore efficient and layered. ipv6ofAddressAllocation is more flexible and redundancy in the network can be reducedFlowto improve the overall operation of the networkEfficiency
6. Better mobility
ipv6Mobile supportipv6（mipv6protocol that allows mobile devices to maintain the same IP while maintaining the same IPAddresscase to switch to a different network. This provides greater flexibility and convenience in the use of mobile devices. Maintain the stability and durability of your network connection no matter where your users are.
7. Multicast and network discovery
ipv6Improved multicast and network discovery mechanisms to make it possible for multiple devices to be interactiveCommunicationsMore efficient and reliable. With multicast, one device can send the same data to multiple devices at the same time, reducing the burden of network transmission and improving data transmissionEfficiency
8. There is no broadcasting
Compared toipv4ipv6The traditional broadcasting mechanism was eliminated and multicast and neighbor discovery protocols were introduced. This change reduces redundancy in the networkFlowto improve the overall performance of the network.
Due toipv6AddressThe number is almost unlimited, and theoretically, each device can be assigned a globally unique oneipv6Address。This makes it possible for external networks (e.g. the Internet) to directly access intranet devices without the need to use e.gipv4Port mappingwithNAT penetrationTechnology. This is necessary for the needRemote accessScenarios for systems or devices are very helpful, such as home automation systems or remote monitoring cameras, etc. However, it should be noted that directly exposing intranet devices to the public network also brings security risks. To ensure the security of data and devices, appropriate security policies and safeguards need to be in place, such as:FirewallsIntrusion detection systemsand real-time security monitoring, etc.
Turn on broadbandipv6It is a necessary measure to meet the needs of future network development. ipv6As a next-generation Internet protocol, more IP is providedAddress, simplified network configuration, end-to-end connectivity, enhanced security, more efficientRouting, better mobility, multicast and network discovery, and no potential benefits such as broadcasting. Turn on broadbandipv6It not only improves the network experience of individual users, but also reduces network latency and improves data transmissionEfficiency, also forInternet of ThingsThe advent of the era provides a reliable network infrastructure.
ForCarriersAnd the country, actively promoteipv6It is an important step to adapt to the development trend of the Internet and can improve the future of the entire networkCompatibilityand scalability. However, in useipv6We also need to pay attention when networkingData Securityand privacy protection, take appropriate security measures to protect personal information and device security. Inipv6We expect a more advanced and stable Internet experience, and moreInternet of ThingsApplication and development of technology.
