How many bit ipv4
WebIPv6 uses 128-bit addresses as opposed to the 32-bit addresses used by IPv4, allowing for a substantially larger number of possible addresses. With each bit corresponding to a ‘0’ or ‘1’, this theoretically allows 2^128 combinations or 340 trillion, trillion, trillion addresses. ... which are pervasive in many IPv4 networks and ...

Easy answer: because Vint Cerf decided so. He thought that he was designing an experimental protocol and considered 32-bits to be more than sufficient for that purpose; he did not expect IPv4 to be used in production systems and so no greater thought was given to the size of the address space. fl2406ww/ss10http://www.steves-internet-guide.com/ipv4-basics/ cannot log in to att emailWebJan 19, 2024 · This leaves 1 bit for the host-id portion of the IP address. Normally a host-id of all zeros is used to represent the network or subnet, and a host-id of all ones is used to represent a directed broadcast.
