RFC 1918 Review




The Request for Comment 1918 (RFC 1918) is a forum that has different approaches of allocating private IP addresses on the Transmission Control Protocol and Internet Protocol systems. It is also described as the Address Allocation for Private Internets and coordinates its activities with the Network Address Tunneling (NAT).




The RFC 1918 utilizes different methods in preventing the overloads on earlier public internet protocol addresses. It enhances the extension of several IP addresses that are active in the Internet Protocol version 4 (IPv4) before the version six internet protocol was introduced.

The guidelines of how the IP addresses are assigned in a private network by a networking system was proposed by the Request for Comment 1918. There are particular ranges of internet protocol address that are non-routable on the internet and are reserved by the RFC 1918. These include the range from 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, and 192.168.0.0 to 192.168.255.255. Any of the addresses that can be situated within the ranges are categorized in a private networking system with a special address within the local area.

Devices that are located within the network can interact using the Network Address Tunneling over the internet. It is effective in describing an internet protocol address that has been used in a single system to other addresses in a different network. The RFC 1918 addresses are often withhold for private use by the internet standard groups. NAT is efficient in providing the transmission or sharing of files from a single public IP address to other several devices.

RFC 1918 addresses can be routed within an enterprise because the private hosts are capable of interacting with the other hosts in the enterprise. RFC1918 needs the DNS data of the RFC 1918 to be hidden and should not appear outside the enterprise. The addresses can be used at home or work places with local area networks and majorly utilizes the version 4 internet protocol.

There are conditions in which the RFC 1918 addresses should not be hidden on the Wide Area Networks (WAN). It involves a situation where the internet service provider allocates the address to end users. Traffic should not be blocked if the assigned address is meant for clients.

The Internet Service Providers can assign the private addresses and create their personal NAT to allow for customer traffic to the public networks. RFC 1918 is usually termed as the Internet addressing architecture and majorly operates with standards that are set by the for the fourth version internet protocol (IPv4).




The Request for Comment is established by the Internet Engineering Taskforce (IETF) and is a formal document which is usually reviewed by parties interested. No comments are usually altered on the committee drafting that is approved to be the internet standards.

The final version is what is accepted and incorporated as the required standards. Not all RFCs are formal in nature. Though adjustment may arise in situations where subsequent RFCs that would like to expand on all aspects of the initial Request for Comment.
