A Canonical Name (CNAME) record is a type of resource record in the Domain Name System (DNS) that maps one domain name (an alias) to another (the canonical name). [ 1 ] This can prove convenient when running multiple services (like an FTP server and a web server , each running on different ports) from a single IP address .
Route table showing internet BGP routes . In computer networking, a routing table, or routing information base (RIB), is a data table stored in a router or a network host that lists the routes to particular network destinations, and in some cases, metrics (distances) associated with those routes.
Observability: Static routes themselves do not propagate, which means that in a network built using only static routes it is hard to get a big picture of all present routes unless monitored. Dynamic routing protocols often transmit topology information or can be connected to debugging tools such as a Looking Glass server.
A route is defined as a pairing between a destination and the attributes of the path to that destination, thus the name, path-vector routing; The routers receive a vector that contains paths to a set of destinations. [3]
