What are the globally scoped multicast addresses?
unique addresses that are public domain addresses
Which class of IP addressing is being used when multicast messages are being sent?
For multicast, ip addresses in the range of 224.0.0.0 - 239.255.255.255 are used.
Which address prefix range is reserved for IPv4 multicast?
The address prefix range reserved for IPv4 multicast is from 224.0.0.0 to 239.255.255.255. This range is designated for multicast communication, allowing the transmission of data to multiple hosts simultaneously. Within this range, certain addresses are further reserved for specific purposes, such as 224.0.0.1 for all hosts on the local network.
What are the differences between a unicast IP address and a multicast IP address in IPv4 name at least three please?
The difference is in the IP range. The multicast IP range is 224.0.0.0 - 239.255.255.255
What is the range of addresses allocated by IANA for public use?
The Internet Assigned Numbers Authority (IANA) allocates a range of addresses for public use in the IPv4 address space, which is from 0.0.0.0 to 223.255.255.255. However, the usable range for public addresses is primarily from 1.0.0.0 to 223.255.255.255, since certain blocks are reserved for special purposes (like private networks and multicast). In IPv6, the global unicast address space ranges from 2000::/3 to 3fff:ffff:ffff:ffff:ffff:ffff:ffff:ffff.
What type IPv6 address is globally routable and reachable on the IPv6 of the Internet?
Globally routable and reachable IPv6 addresses are known as global unicast addresses. These addresses fall within the range of 2000::/3 and are assigned by the Internet Assigned Numbers Authority (IANA) to ensure unique identification across the Internet. They are used for direct communication over the Internet and can be routed by routers worldwide.
What are multicast scope?
Multicast scope refers to the range or extent to which multicast traffic is allowed to propagate across a network. It is typically categorized into several levels: link-local (limited to a single network segment), site-local (restricted to a specific site or organization), and global (accessible across the entire internet). These scopes help manage multicast traffic efficiently, ensuring that it reaches the intended audience without unnecessary congestion on networks. Understanding multicast scope is essential for network design and optimizing resource use in multicast applications.
How many possible IP addresses are there?
IP addresses range from 0.0.0.0 to 255.255.255.255, with the numbers 0-255 represented in each of the four segments of the address. This results in a total of 4,294,967,296 possible addresses. Note that many addresses are reserved for private or multicast use. Therefore, the actual number of available addresses is much lower than the 4.3 billion theoretical addresses.
Which ip blocks are reserved for private networks?
IPv4 private addresses:Class A addresses in the range 10.0.0.0 to 10.255.255.255Class B addresses in the range 172.16.0.0 to 172.31.255.255Class C addresses in the range 192.168.0.0 to 192.168.255.255IPv6 private addresses:All IPv6 addresses with the prefix FC00::/7 are regarded as private.
An organization has decided to use IP addresses in the range 172.20.128.0 to 172.20.143.255 Which combination of network ID and subnet mask identifies all IP addresses in this range?
An organization has decided to use IP addresses in the range 172.20.128.0 to 172.20.143.255. Which combination of network ID and subnet mask identifies all IP addresses in this range?
What class License do APIPA addresses use?
APIPA addresses are in the range 169.254.0.1 through 169.254.255.254. These would be in the Class B address range.
Can you subnet a class D block and why?
Class D IP addresses, which range from 224.0.0.0 to 239.255.255.255, are designated for multicast groups rather than traditional host addressing. As such, they do not support subnetting in the same way as Class A, B, or C addresses, since they are not intended for individual host allocation. Subnetting is primarily used to create multiple networks from a single larger network, which is not applicable to Class D. Therefore, subnetting a Class D block is not possible or meaningful in conventional networking.
