IPv6 can use a DHCPv6 server for the allocation of IPv6 addressing to hosts. Another IPv6 addressing option utilizes the IPv6 Neighbor Discovery Protocol (NDP) to discover the first portion of the IPv6 address (network prefix) from local routers, and the host can create its own host ID. What standard is commonly used by an IPv6 host to generate its own 64-bit host ID

Following are the answer to this question.

Explanation:

It is a mechanism, that is also known as EUI-64, which enables you an automatic generation of its specific host ID. It using the device on the 48-bit MAC address, which helps to construct the special 64-bit host ID. It also helps you to build a DHCP-type IPv6 network, that's why we can say that the above-given standard is widely used to create a 64-bit host ID on IPv6 servers.

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
