* Registration Fee: The charge for registering, a domain name. InterNIC' registration fee covers the cost of processing the initial registration and maintaining the domain name record for two years. For domain names with registration dates on or after April 1, 1998, the fee is 70.00 USD. After the initial two-year period, the domain name is subject to renewal (re-registration) and the renewal (re-registration) fee will be due on an annual basis if the registrant wishes to renew the domain name's registration.

* Registration Forms: Forms that are used to submit and process registration requests. These forms are used to register new domain names, new contacts for domain names, and new hosts (name servers) as well as to update domain name, contact, and host records. There are both Web versions and plain text (ASCII) versions of the forms.

* Registry: A registry is responsible for delegating Internet addresses such as Internet Protocol (IP) numbers and domain names, and keeping a record of those addresses and the information associated with their delegation. A domain name registry, also called Network Information Centre (NIC), is part of the Domain Name System (DNS) of the Internet which converts domain names to IP addresses. It is an organisation that manages the registration of Domain names within the top-level domains for which it is responsible, controls the policies of domain name allocation, and technically operates its top-level domain. It is potentially distinct from a domain name registrar. Domain names are managed under a hierarchy headed by the Internet Assigned Numbers Authority (IANA), which manages the top of the DNS tree by administrating the data in the root nameservers. IANA also operates the .int registry for intergovernmental organisations, the .arpa zone for protocol administration purposes, and other critical zones such as root-servers.net. IANA delegates all other domain name authority to other domain name registries such as VeriSign. Country code top-level domains (ccTLD) are delegated by IANA to national registries such as DENIC in Germany, or Nominet in the United Kingdom. Examples of regional IP registries include Asian-Pacific Network Information Center (APNIC), American Registry for Internet Numbers (ARIN), and Reseaux IP Europeens (RIPE). Examples of domain name registries include InterNIC's InterNIC operation (.com, .net, and .org) and the ISO3166 country code registries (e.g., .fr, .de, .uk, and .us).

* Renewal (Re-registration): The process of reinitiating a domain name's registration for a specified period of time. Renewing an existing domain name with InterNIC is accomplished by simply paying the renewal (re-registration) fee which covers one year of continued registration and maintenance, and agreeing to be bound by the terms and conditions of the then existing Domain Name Registration Agreement, including the Domain Name Dispute Policy.

* Renewal (Re-registration) Fee: The charge for renewing an existing domain name registration. InterNIC's renewal (re-registration) fee covers one year of maintenance for the domain name record and is assessed each year on the anniversary of the original registration. For domain names with anniversary dates on or after April 1, 1998, the fee is 35.00 USD.

* Renewal (Re-registration) Notice: A notice sent to registrants 60 days before the anniversary of their registration date to let them know that their domain name will be due for renewal (re-registration) and that an invoice will be sent for the renewal (re-registration) fees.

* Renewal date: The date on which the periodic maintenance fee paid for a given domain name runs out. On or before this date, the domain name owner must pay another 1-10+ years of domain name maintenance fees in order to keep the rights to the domain name. If the renewal date is allowed to pass without payment, the domain name becomes expired and will eventually drop.

* Reseller: A company/person that sells domain names through registry services provided by an ICANN approved registrar.

* RNCA (Registrant Name Change Agreement) Search Engine: A site which searches the web for sites which are relevant for a given search query.
