The Internet was born in the USA and was financed for many years by American taxpayers. This situation became no longer viable in the 90s resulting in the creation of a new structure of Internet organization. End users participate in financing this structure by paying their Internet providers for connectivity and for registration of their subdomains. Providers then put part of these payments towards the activities of these international organizations. Two links from the original structure are important for us as ordinary Internet users RFC-editor which publishes the RFC standards http . This link is a source for Internet standards for us. To better understand the process of Internet standards it is recommended to look at RFC 2026. The Internet Assigned Numbers Authority IANA . Its home page http states Dedicated to preserving the central coordinating functions of the global Internet for the public good. IANA maintains three very important registers o The Top-Level Domain TLD register http . o A register of allocation of the addresses in Internet space IP version 4 addresses as well as IP version 6 addresses . assigning the address space to the individual regions of the world http ipaddress ip-addresses .htm . o Assigned numbers http . a register of other assigned numbers contains not only numbers for individual protocols but also for example allocation of AS numbers for individual regions of the world. If you study packets of certain protocols in detail and come across a certain field with a value you do not know you will appreciate Assigned Numbers. Assigned Numbers were originally published from time to time as RFC for example RFC 1700 . This mechanism was later replaced see RFC 3232 .
