The Business plan costs $12 per user, per month and offers all the same email benefits as the Basic plan. Like the entry-level plan, users have the option of setting up an approved sender list, allow a co-worker’s email using the same email domain to bypass the spam check or to increase the stringency of Google’s default spam filtering. However, unlike the Basic plan, this tier gives users a vault for ediscovery of documents as well as archiving.
The character set allowed in the Domain Name System is based on ASCII and does not allow the representation of names and words of many languages in their native scripts or alphabets. ICANN approved the Internationalized domain name (IDNA) system, which maps Unicode strings used in application user interfaces into the valid DNS character set by an encoding called Punycode. For example, københavn.eu is mapped to xn--kbenhavn-54a.eu. Many registries have adopted IDNA.
A fully qualified domain name (FQDN) is a domain name that is completely specified with all labels in the hierarchy of the DNS, having no parts omitted. Labels in the Domain Name System are case-insensitive, and may therefore be written in any desired capitalization method, but most commonly domain names are written in lowercase in technical contexts.
