The hosts file is one of several system facilities that assists in addressing network nodes in a computer network. It is a common part of an operating system's Internet Protocol (IP) implementation, and serves the function of translating human-friendly hostnames into numeric protocol addresses, called IP addresses, that identify and locate a host in an IP network.
resolv.conf is a computer file used in various operating systems to configure the system's Domain Name System (DNS) resolver.The file is a plain-text file usually created by the network administrator or by applications that manage the configuration tasks of the system.
The Internet has two main name spaces, IP addresses and the Domain Name System. HIP separates the end-point identifier and locator roles of IP addresses. It introduces a Host Identity (HI) name space, based on a public key security infrastructure. The Host Identity Protocol provides secure methods for IP multihoming and mobile computing.
Record to describe well-known services supported by a host. Not used in practice. The current recommendation and practice is to determine whether a service is supported on an IP address by trying to connect to it. SMTP is even prohibited from using WKS records in MX processing. [16] NB 32 RFC 1002
Each host listens on the mDNS port, 5353, transmitted to a well-known multicast address and resolves requests for the DNS record of its .local hostname (e.g. the A, AAAA, CNAME) to its IP address. When an mDNS client needs to resolve a local hostname to an IP address, it sends a DNS request for that name to the well-known multicast address; the ...
The current namespace architecture used by the Internet Protocol uses IP addresses for two separate functions: as an end-point identifier to uniquely identify a network interface within its local network addressing context; as a locator for routing purposes, to identify where a network interface is located within a larger routing context
