    First, the number of IPv4 address bits is 32 bits, that is, the computer with up to 2 32-th power can be connected to the Internet.

    Second, IPv6 uses a 128-bit address length to provide an address with almost unlimited restrictions. The IPv6 actually assignable address is estimated in a conservative way, and more than 1000 addresses can be allocated per square meter of the entire earth.

    Third, the biggest difference between IPv4 and IPv6 is that the actual address that can be assigned is different. In the design process of IPv6, in addition to solving the address shortage problem once and for all, it also considers other problems that are not well solved in IPv4, mainly end-to-end IP connection, quality of service (QoS), security, multicast, mobile. Sex, plug and play, etc.

    The biggest difference between IPV6 and IPV4 can be listed as the following points

    (1) IPv4 can provide 4,294,967,296 addresses, and IPv6 will increase the original 32-bit address space. To 128 bits, the number is 2 to the 128th power. It can provide 6×1023 network addresses per square meter on the earth and will not be exhausted in the foreseeable future.
    (2) IPv4 uses Address Resolution Protocol (ARP), which uses the Multi-Neighbor Solicitation message instead of Address Resolution Protocol (ARP).
    (3) In IPv4, the router does not recognize the payload for QoS processing of quality of service. The IPv6 router uses the Flow Label field to identify the payload for QoS processing for quality of service.
    (4) The loop address of IPv4 is:, and the loop address of IPv6 is: 000:0000:0000:0000:0000:0000:0000:0001 can be abbreviated as ::1.
    (5) In IPv4, Dynamic Host Configuration Protocol (DHCP) implements automatic setting of host IP address and its related configuration. A DHCP server has an IP address pool. The host leases the IP address from the DHCP server and obtains related configuration information (such as the default gateway, DNS server, etc.), thereby achieving the purpose of automatically setting the host IP address. IP v6 inherits this automatic configuration service of IPv4 and calls it stateful autoconfiguration. M.pcwenku.com Feeds
    (6) IPv4 uses the Internet Group Management Protocol (IGMP) to manage the membership of the local subnet group, and IPv6 replaces IGMP with Multicast Listener Discovery (MLD) messages.
    (7) Built-in security. Developed by the IETF, IPSec is an industry standard that ensures that secret, complete, and authentic information traverses public IP networks. IPsec is no longer a supplement to the IP protocol. In IPv6, IPsec is a function of IPv6 itself. IPv4 selectively supports IPSec, and IPv6 automatically supports IPSec.
    (8) Better QoS support. QoS is a security mechanism of the network. Usually, QoS is not needed, but it is necessary for critical applications and multimedia applications. When the network is overloaded or congested, QoS ensures that important traffic is not delayed or discarded, while ensuring efficient network operation. In the IPv6 header, how to handle and identify the transmission is defined. In the IPv6 header, Flow Label is used to identify the transmission, so that the router identification and special processing belong to a packet of traffic. Traffic refers to a series of packets between source and destination. Because the transmission is identified in the IPv6 header, QoS support is achieved even through IPSec-encrypted packet payload.

    Internet Protocol Version 4 is the Internet Basic Protocol, which is the basic protocol for Internet services; Internet Protocol Version 6 is the local broadband network to provide business management agreements. You want to use broadband networking, these two protocols are indispensable!

    It’s no different, it’s said that it’s just an improvement of individual functions, such as repairing vulnerabilities and preventing intrusions.

    The 6 version is based on 4, a more advanced protocol, faster than 4. However, I don’t think there is much difference.

    The main difference lies in:
    1, different address space, IPv4 provisions The IP address length is 32, and the length of the IP address in IPv6 is 128.

    2. The routing table size is different. The IPv6 routing table is smaller than IPv4.

    3. IPv6 multicast support and convection support are stronger than IPv4.

    4. Different security, IPv6 is more secure. When using IPv6 network, users can encrypt data at the network layer.

    5. Different protocol extensions, IPv6 allows the protocol to be extended and IPv4 is not allowed.

    Basically similar, mainly increasing the number.

    The difference between IPv6 and IPv4:
    Greater address space. In IPv4, the IP address length is 32, that is, there are 2^32-1 addresses; and the length of the IP address in IPv6 is 128, that is, there are 2^128-1 addresses.
    Smaller routing table. The IPv6 address allocation follows the principle of aggregation (Aggregation) at the beginning, which enables the router to use a record (Entry) to represent a subnet in the routing table, which greatly reduces the length of the routing table in the router and improves router forwarding. The speed of the packet.
    Enhanced Multicast support and flow-control support. This has enabled the development of multimedia applications on the network to provide a good network platform for quality of service (QoS) control.
    Added support for Auto-configuration. This is an improvement and extension of the DHCP protocol, making the management of the network (especially the local area network) more convenient and faster.
    Higher security. In the IPv6 network, users can encrypt the data of the network layer and IP. Packet verification, which greatly enhances network security.
