Multicast IP Address To MAC Address Mapping

Multicast IP Address To MAC Address Mapping In this lesson, we discuss the process of converting a multicast ip address to a multicast mac address. it is very important to keep in mind that network devices work with ip and mac addresses only in binary. Here you need to write a function to translate a multicast address to valid mac address. all inputs are valid multicast ip addresses, you must return a string with mac address.

Multicast IP Address To MAC Address Mapping

Multicast IP Address To MAC Address Mapping During encapsulation of a multicast packet, a specific mapping algorithm is used to map the 28 bit multicast ipv4 addresses to the 23 bit multicast mac addresses. When you send something to a host on a different network, the source mac is the sending host, and the destination mac is the router you are using to send to the distant network. Every multicast ip address (group address) is mapped to a special mac address that allows ethernet interface to identify multicast packets to a specific group. in class d every single ip represent a multicast group. First, we’ll figure out which multicast mac address maps to which 32 multicast ip addresses. you can use the following table to calculate between decimal, hexadecimal, and binary:.

First, we’ll figure out which multicast mac address maps to which 32 multicast ip addresses. you can use the following table to calculate between decimal, hexadecimal, and binary:. Every ipv4 multicast ip will always start with the same 4 bits: 1110. that really means that we don't need to worry about copying them, as they're well known. that leaves us with 5 bits not copied into the mac address. these are lost. there are no tricks here. Here’s how to figure out what mac address your ip address maps to: 1000000 00000000 00000001. now we need to convert these 23 bits into hexadecimal. you need to take 4 binary bits and convert them to hexadecimal: that gives us: 40:00:01. the first part of a multicast mac address always starts with 01:00:5e so let’s put that in front:.
