DNS-SD (DNS Service Discovery [16]) allows clients to discover a named list of service instances and to resolve those services to hostnames using standard DNS queries. The specification is compatible with existing unicast DNS server and client software, but works equally well with mDNS in a zero-configuration environment.
Multicast DNS (mDNS) is a computer networking protocol that resolves hostnames to IP addresses within small networks that do not include a local name server.It is a zero-configuration service, using essentially the same programming interfaces, packet formats and operating semantics as unicast Domain Name System (DNS).
Head End Replication is only available if using BGP EVPN. It is less efficient than multicast and does not scale well but it is simpler to implement if you do not have a multicast-enabled infrastructure. In Head End Replication, when BUM arrives, the VTEP creates several unicast packets and sends one to each VTEP that supports the VNI. [16]
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 ...
[16] In IPv4 it is very difficult for an organization to get even one globally routable multicast group assignment, and the implementation of inter-domain solutions is arcane. [17] Unicast address assignments by a local Internet registry for IPv6 have at least a 64-bit routing prefix, yielding the smallest subnet size available in IPv6 (also 64 ...
In computer networking, unicast is a one-to-one transmission from one point in the network to another point; that is, one sender and one receiver, each identified by a network address. [ 1 ] Unicast is in contrast to multicast and broadcast which are one-to-many transmissions.
The first iPhones to have Touch ID are the iPhone 5s and models up to iPhone 8 Plus and iPhone SE have Touch ID installed. Face ID. When iPhone X debuted without a home button, Apple introduced ...
UPnP logo as promoted by the UPnP Forum (2001–2016) and Open Connectivity Foundation (2016–present). Universal Plug and Play (UPnP) is a set of networking protocols on the Internet Protocol (IP) that permits networked devices, such as personal computers, printers, Internet gateways, Wi-Fi access points and mobile devices, to seamlessly discover each other's presence on the network and ...
