This is a list of the instructions that make up the Java bytecode, an abstract machine language that is ultimately executed by the Java virtual machine. [1] The Java bytecode is generated from languages running on the Java Platform, most notably the Java programming language.
Java bytecode is the instruction set of the Java virtual machine (JVM), the language to which Java and other JVM-compatible source code is compiled. [1] Each instruction is represented by a single byte , hence the name bytecode , making it a compact form of data .
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header. Both fields are eight bits wide.
The term subnet mask is only used within IPv4. Both IP versions however use the CIDR concept and notation. In this, the IP address is followed by a slash and the number (in decimal) of bits used for the network part, also called the routing prefix. For example, an IPv4 address and its subnet mask may be 192.0.2.1 and 255.255.255.0, respectively.
The Internet checksum, [1] [2] also called the IPv4 header checksum is a checksum used in version 4 of the Internet Protocol (IPv4) to detect corruption in the header of IPv4 packets. It is carried in the IPv4 packet header, and represents the 16-bit result of the summation of the header words. [3] The IPv6 protocol does not use header checksums.

IPv4 Multicast: [39] Insert the low 23 bits of the multicast IPv4 address into the Ethernet address [40]: §2.1.1 33-33-xx locally administered. 33-33-00-00-00-00 through 33-33-FF-FF-FF-FF: 0x86DD IPv6 multicast: [41] The low 32 bits an Ethernet address for IPv6 multicast traffic are the low 32 bits of the multicast IPv6 address used.
IVI Translation refers to a stateless IPv4/IPv6 translation technique. [1] It allows hosts in different address families (IPv4 and IPv6) communicate with each other and keeps the end-to-end address transparency. [2] Stateless NAT64 can be used in 4 different scenarios: [3] An IPv6 network to the IPv4 Internet; The IPv4 Internet to an IPv6 network
