How Big is the Mac Address Space? the Ipv4 Address Space? the Ipv6 Address Space??

Solutions to Sample Questions on Link Layer

4 How big is the MAC address space, the IPv4 address space and the IPv6 address space? Answer: 248 MAC addresses; 232 IPv4 addresses; 2128 IPv6 addresses. 5 Why is an ARP query sent within a broadcast frame?

How Big is the Space of MAC Address?

This 48bit address space contains potentially 2 48 over 281 trillion possible MAC addresses. The IEEE manages allocation of MAC addresses, originally known as MAC48 and which it now refers to as EUI48 identifiers.

How Big is the IPv6 Address Space?

IPv6 uses 128bit 2 128 addresses, allowing 3.4 x 10 38 unique IP addresses . This is equal to 340 trillion trillion trillion IP addresses. IPv6 is written in hexadecimal notation, separated into 8 groups of 16 bits by the colons, thus 8 x 16 = 128 bits in total.

How Big is IPv4 Space?

Both IPv4 and IPv6 addresses come from finite pools of numbers. For IPv4, this pool is 32-bits (2 32 ) in size and contains 4,294,967,296 IPv4 addresses. The IPv6 address space is 128-bits (2 128 ) in size, containing 340,282,366,920,938,463,463,374,607,431,768,211,456 IPv6 addresses.

Why is an ARP Query Sent Within a Broadcast Frame Why is ARP Response Sent Within a Frame with a Specific Destination MAC Address?

Why is an ARP response sent within a frame with a specific destination MAC address? An ARP query is sent in a broadcast frame because the querying host does not which adapter address corresponds to the IP address in question.

Does a MAC Address Mean Apple Invented It?

These MAC addresses are 48 bits or 6 bytes long, so they are also known as MAC48 or EUI48. EUI stands for Extended Unique Identifier.

Which Destination MAC Address is Used in an ARP Request Frame?

The purpose of an ARP request is to find the MAC address of the destination host on an Ethernet LAN. The ARP process sends a Layer 2 broadcast to all devices on the Ethernet LAN. The frame contains the IP address of the destination and the broadcast MAC address, FFFF. FFFF.

What MAC Address is an ARP Broadcast Sent To?

ARP request packets are sent to the broadcast addresses ( FF:FF:FF:FF:FF:FF for the Ethernet broadcasts and 255.255. 255.255 for the IP broadcast ). Let's say that Host A wants to communicate with host B. Host A knows the IP address of host B, but it doesn't know the host B's MAC address.

What is the Destination Address of a Frame Containing an ARP Request?

The frame type is ARP (0x0806). The destination mac address is ff:ff:ff:ff:ff:ff.
