IPv6 - Essay moralThe 32-bit parcel outing system employs packet switching to facilitate communication. IPv4 can thus be treated as an climb of IPV4, to improve the IP protocol system. There atomic number 18 a number of significant dereferences between the cardinal protocols that will be essential in determining ones choice for usage. Discussed below are the major dissimilaritysAddress length- IPv4 is a 32 bit address while IPv6 is a 128 bit. This is the basic difference observable at a glance. These DNS names differ by a wide margin if compared by the number of addresses each can yield. In fact, to completely c everywhere the IPv6 address, it is written in hexadecimal number as compared to IPv4 written in dotted decimal numbers. This forms of representation are all interpreted in form of binary numbers by the computers (Huitema, 1996).Packet header-generally, packet headers are always affixed at the start of Internet protocol addresses. It normally contains the address of the destination of a given packet. IPv4 has got packet headers only. This differs from IPv6 that has the header, although with to a greater extent advanced functionalities. The header of IPv4 is 20 bits as compared to the 40 bits of IPv6. The advancement in the header allows addition of point of reference headers, a functionality not provided for by IPv4 computers (Huitema, 1996).Address resolution- the process of address resolution involves mapping of various IP addresses to the MAC address or rather, a link address. IPv4 employs the RFC 826. This is an Ethernet address resolution protocol. This resolution protocol has over the years exposed users to cyber threats because the protocol is within the link layer. IPv6 on the other hand makes use of live discovery Address resolution. Its protection is secured because the IPSec is employed to secure the connection in tunnel or channelize mode (Amoss, & Minoli, 2008).Configuration- users of IPv4 have to ensure all configurations are done prior to internet usage. The IP address and routes
