Every computer has the ability to establish a connection using an IP address https://acortaz.eu/ipv4-e-ipv6-comparacion/ or Internet protocol. The two most widely used versions of the Internet protocol that are now the only ones in existence are IPv4 and IPv6. Comparando IPv4 and IPv6, se puede determinar que tantos son utilizados para identificar todos los dispositivos conectados a la red, aunque ambas poseen características distintas y distintas.
The main differences between IPv4 and IPv6
La IPv6 tiene un tamaño de 128 bits, whereas que la dirección y la primera tiene un máximo di 32 bits. La IPv6 tiene 8 campos de encabezado, mientras como la IPv4 tiene 12. Conversely, the length of these fields is 20 bytes for IPv4 and 40 bytes for IPv6.
Since IPv6’s direction-finding method is based on an alphanumeric model rather than a numeric model, it can obtain a greater number of directions than IPv4 can. This has allowed for improvements.
Broadcast, unicast, and multicast are the types of direction that IPv4 has, but IPv6 has Anycast, multicast, and unicast. Entre los dos, la IPv4 es el único que soporta VLSM, opción de máscara la subred de longitud variable. However, IPv6 takes the lead because it has autoconfiguring capabilities, https://acortaz.eu/ipv4-e-ipv6-comparacion/ unlike IPv4, which must be manually configured via a dynamic host configuration protocol known as DHCP.
IPv4 uses a network address translation, or NAT, while IPv6 supports redirection and has a large space for storing directions. El tamaño la los paquetes es de 1208 bytes per la IPv6 y de 577 bytes para la IPv4, no uses la máscara de dirección que utiliza la IPv4.
Benefits of IPv6 in Terms of Security
IPv6 was developed as an enhancement of IPv4 and provides additional protocols to ensure secure network communications. This is made possible via IP Security, or IPSec,https://acortaz.eu/ipv4-e-ipv6-comparacion/ which has authentication headers, or AH; an encapsulated security payload, or ESP; an Internet security association; and a key management protocol, or ISAKMP.
These components ensure network communications and functions such as:
1. Checking the process of a datagram or packet
2. Identify whether a package’s gearbox has been altered
3. Avoid having hackers create phoney packages.
4. Add authentication caps.
5. Safeguard data transmission
Define the security attributes.
Execute cifrado desde un extremo al otro.
Another significant benefit is that IPv6 makes use of the Secure Neighbour Discovery (SEND) protocol, which looks for a secure number resolution. Because of this, hackers will encounter difficulties when attempting to manipulate data transfers or restrict traffic between two hosts. In order for IPv6 to function properly, the user must install an antivirus and firewall on their computer.
