That means the results will not include a /n range with n > 64. |results=all Show all possible summaries, including any with a range that is too large to block (/n less than /16 for IPv4 or /19 for IPv6). Also changes the default allocation from 64 to 128. |results=n The number n can be 1 to 100; the default is 10. No more than n summaries are ...
As shown in the example below, in order to calculate the directed broadcast address to transmit a packet to an entire IPv4 subnet using the private IP address space 172.16.0.0 / 12, which has the subnet mask 255.240.0.0, the broadcast address is calculated as 172.16.0.0 bitwise ORed with 0.15.255.255 = 172.31.255.255. Directed broadcasts always ...
The original list of IPv4 address blocks was published in September 1981. [3] In previous versions of the document, [19] [20] network numbers were 8-bit numbers rather than the 32-bit numbers used in IPv4. At that time, three networks were added that were not listed earlier: 42.rrr.rrr.rrr, 43.rrr.rrr.rrr, and 44.rrr.rrr.rrr.
Internet Protocol version 4 (IPv4) is the first version of the Internet Protocol (IP) as a standalone specification. It is one of the core protocols of standards-based internetworking methods in the Internet and other packet-switched networks. IPv4 was the first version deployed for production on SATNET in 1982 and on the ARPANET in January
The 232.0.0.0 / 8 (IPv4) and ff3x:: / 32 (IPv6) blocks are reserved for use by source-specific multicast. GLOP [13] The 233.0.0.0 / 8 range was originally assigned as an experimental, public statically-assigned multicast address space for publishers and Internet service providers that wished to source content on the Internet.

The Link-Local Multicast Name Resolution (LLMNR) is a protocol based on the Domain Name System (DNS) packet format that allows both IPv4 and IPv6 hosts to perform name resolution for hosts on the same local link. It is included in Windows Vista, Windows Server 2008, Windows 7, Windows 8, Windows 10. [1]

Broadcast packets make use of the broadcast MAC address FF:FF:FF:FF:FF:FF. IPv4 multicast packets are delivered using the Ethernet MAC address range 01:00:5E:00:00:00 through 01:00:5E:7F:FF:FF (with an OUI owned by the IANA). This range has 23 bits of available address space. The first octet (01) includes the broadcast/multicast bit.
