The Bonjour name gets stored in the following property list file: Or if you try setting a Bonjour name more that 63 character, for example 64 characters, it will not allow you to paste or type more than 63 characters. If you try to use Bonjour illegal characters with the OS X computer name they are converted.įor example, if I tried to set the computer name to “-” (dash), the Bonjour name is converted to “Macintosh.local” Or if you want a custom Bonjour not based on the computer name, then select the “ Edit…” button under the “ Computer Name” text box and enter the custom Bonjour name. Select System Preferences -> Sharing, then enter or modify the “Computer Name” text box and press RETURN. To set Bonjour name you can do it manually using the OS X built-in graphical tools. No other symbols, punctuation characters, or white space are permitted. However, a subsequent specification (RFC 1123) permitted hostname labels to start with digits.
The original specification of hostnames in RFC 952, mandated that labels could not start with a digit or with a hyphen, and must not end with a hyphen. The Internet standards for protocols mandate that component hostname labels may contain only the ASCII letters ‘a’ through ‘z’ (in a case-insensitive manner), the digits ‘0’ through ‘9’, and the hyphen (‘-‘). Both in RFC 1035 section 2.3.1 and as clarified in RFC 2181 section 11.

Note – Windows does not permit computer names that exceed 15 characters, and you cannot specify a DNS host name that differs from the NETBIOS host name.ĭNS limits the length of each label in RFC 1035 – however, that limit is actually 63. The maximum length of the host name and of the fully qualified domain name (FQDN) is 63 bytes per label and 255 bytes per FQDN.
Naming Guidelinesīecause they are intended to be browsed rather than typed, service instance names can be any Unicode string encoded with UTF-8, up to 63 octets (bytes) in length.įor example, see the following Apple Developer documentation on the web site:īonjour Name Maximum Length – 63 Characters

Bonjour components may also be included within other software such as iTunes and Safari. Bonjour can also be installed onto computers running Microsoft Windows.

The hostname began as a simple string of alphanumeric characters (and possibly a hyphen) and has evolved to its current definition, where hostname means a Fully Qualified Domain Name (FQDN) that absolutely and uniquely identifies every computer hooked up to the Internet. With the advent of the Internet, the requirements for enabling computers to communicate with each other on a network included the concept of the hostname. Computers have always needed unique addresses to talk to each other. Computers are also named to differentiate one machine from another and to allow for such activities as network communication. A person’s name, for instance, comprises a set of alphabetic characters that allows a person to be individually addressed. 3 Likes Hostname, Computer Name, Local HostName… Oh MyĪ name is a label that is used to distinguish one thing from another.
