The subnet router anycast address is the lowest address in the subnet, so it looks like the “network address”. If a router has multiple subnets on the same link, then it has multiple subnet router anycast addresses on that link. [19] The first and last address in any network or subnet is not allowed to be assigned to any individual host.
A wildcard mask is a mask of bits that indicates which parts of an IP address are available for examination. In the Cisco IOS, [1] they are used in several places, for example: To indicate the size of a network or subnet for some routing protocols, such as OSPF. To indicate what IP addresses should be permitted or denied in access control lists ...

Whether software programmed for Linux can run on Android, depends entirely on the extent to which libbionic matches the API of the glibc. 2 libinput [ 15 ] provides device detection via udev , device handling, input device event processing and abstraction.
The Internet Engineering Task Force (IETF) has reserved the IPv4 address block 169.254.0.0 / 16 (169.254.0.0 – 169.254.255.255) for link-local addressing. [1] The entire range may be used for this purpose, except for the first 256 and last 256 addresses (169.254.0.0 / 24 and 169.254.255.0 / 24), which are reserved for future use and must not be selected by a host using this dynamic ...
network identifier: The destination subnet and netmask; metric: The routing metric of the path through which the packet is to be sent. The route will go in the direction of the gateway with the lowest metric. next hop: The next hop, or gateway, is the address of the next station to which the packet is to be sent on the way to its final destination
The prefix length can range from 0 to 128, due to the larger number of bits in the address. However, by convention, a subnet on broadcast MAC layer networks always has 64-bit host identifiers. [13] Larger prefixes (/127) are only used on some point-to-point links between routers, for security and policy reasons. [14]
