An IPv6 multicast address has a most significant byte of 0xff. The amount of IPv6 address which gets "lost" this way isn't as much as first appears. Hexadecimal and whose last four octets are the last four octets of Of the sixteen octets DST through DST, is transmitted to theĮthernet multicast address whose first two octets are the value 3333 To quote section 7 of this RFC in its entirety.Īn IPv6 packet with a multicast destination address DST, consisting In the IPv6 world, the mapping between IPv6 addresses (16 bytes) and MAC addresses is defined by RFC2464.

(You can enter your query into either the "Multicast IP" field or the "Multicast MAC" field) Reserved Multicast Addresses Enter either a multicast IP address or a multicast MAC address into the appropriate field and click the button You can use the tool below to convert multicast IP address to MAC address and back again.

High-bandwidth software download is being transmitted on multicast IP address 224.1.2.3 and IP-aware and will do their multicast filtering based on MAC addresses. Similar) will not affect network performance for all users. Users will only "see" multicast traffic they haveĪctually asked for, so that (for example) a high-bandwidth software download (using Ghost or something This has implications for multicast application design. Rather,Įach multicast MAC address will be shared by 32 IP addresses. Not a one-to-one mapping between multicast IP address and multicast MAC addresses.
Significant 9 bits of the multicast IP address are quite simply ignored and the remainingĢ3 bits are copied into the lowest 23 bits of the MAC address.Īs a consequence of this, 5 bits of "useful" IP address information being scrapped, there is Non-technical reasons which need not detain us here).
Significant three bytes of the MAC address) available into which to encode the IP address.Īctually, it is even worse than this.only the lower 23 bits are available for use (for The astute reader may have noticed a problem by now: There are only 24 bits (the least If we ignore the four most significant bits of the multicast IP address (which,Īs noted earlier, will always be "1110"), that leaves 28 bits of IP address information which Traffic, we would ideally like a one-to-one mapping between multicast IP addresses and multicast Since it is obviously infeasible to have an equivalent of ARP when transmitting multicast If you aren't interested and reading this but just need to do a conversion you can skip ahead to the Address Converter Tool. For IP multicast specifically, the Ethernet prefix In the Ethernet world, a multicast MAC address is distinguished by a binary '1' in the least If you are looking for something to test IP multicast on your network you might like to check out our free (but very unfinished !)
