Internationalized Domain Name (IDN)

IDNs are domain names represented by local language characters. Such domain names could contain characters with diacritical marks as required by many European languages, or characters from non-Latin scripts (for example, Arabic or Chinese). IDNs make the domain name label as it is displayed and viewed by the end user different from that transmitted in the DNS. To avoid confusion the following terminology is used: The A-label is what is transmitted in the DNS protocol and this is the ASCII-compatible (ACE) form of an IDNA string; for example "xn--11b5bs1di". The U-label is what should be displayed to the user and is the representation of the Internationalized Domain Name (IDN) in Unicode; Lastly, the LDH-label strictly refers to an all-ASCII label that obeys the "hostname" (LDH) conventions and that is not an IDN.

register an Internationalized Domain Name (IDN)

Internationalized domain names are registered in the same way as normal domain names. Enter the domain in the native language into the search bar. You will be asked to select which language that you used, please select it from the drop down menu. Please note, not all extensions allow all languages, and not all characters are valid for every language. Please refer to the specific extension for which languages are allowed. Characters used must be in UTF-8.

update my Domain's DNS Records

You can modify records on domains that are using our DNS servers through your control panel. If you have hosting with us, zone changes are done through our hosting control panel. If you are using a third party hosting provider, please contact them for zone changes. Third party hosting providers may need to have their DNS servers comply with RIPE standards.

update Domain Name Servers (DNS)

You may update your DNS settings by logging into your domain administration panel, selecting the domain for which you wish to change the DNS servers and clicking "Edit DNS" on the side bar. Your hosting provider should have provided you with the correct name for the servers, so enter those in the boxes on the screen. The change will take approximately 48 hours, but for some extensions may take significantly longer.

transfer a Domain Name to another Provider's Domain Name Server (DNS)

You may transfer your domain name to another provider's DNS server by logging into your domain administration panel, selecting the domain for which you wish to change the DNS servers, and clicking "Edit DNS" on the side bar. Your hosting provider should have provided you with the correct name for the servers, so enter those in the boxes on the screen. The change will take approximately 48 hours, but for some extensions may take significantly longer.

Primary and Secondary DNS

This refers to the name server computers where the record of your domain name is held. This is needed to register a domain name and we supply this for you unless otherwise specified. Primary and Secondary DNS servers are the two servers we enter into their IP settings under DNS Servers as the computers to ask when the local machine doesn't know the IP address for a given name. Generally, we setup 2 Domain Servers for your security.

What is a Domain Name Server or DNS?

A Domain Name Server or DNS is a computer that holds and stores records of domain names. Simply put, the DNS serves as the "phone book" for the Internet by translating human-friendly computer hostnames into IP addresses. For example, www.example.com translates to 208.77.88.66.

How long or short can a domain name ?

Most domain names have a minimum of 2 and a maximum 63 characters, including the extension (.com, .net, .org). A domain name may contain numbers (0-9), letters (a-z) or dashes (-).

A domain name may not:

•Begin or end with a dash (-).
•Contain special characters, such as(! @#$%&? ~: _)
•Have a dash (-) in the third and/or fourth positions.

register my domain name?

domain registration for all generic top level domains (.com, .net, .org) as well as international domain extensions for approximately 1,000 countries around the world. To register your domain name, simply navigate to our homepage and enter your desired domain in the search box. If the name is available, you may add it to your cart and begin the checkout and registration process. Registration with 101domain requires that you create an account, so if you do not already one, you will be prompted to create one. If you do have an account, you will be asked to login. From there, follow the step-by-step process to complete your domain registration.

What is an IP address?

What is an IP address?
In the most widely installed level of the Internet Protocol (IP) today, an IP address is a 32-bit number that identifies each sender or receiver of information that is sent in packets across the Internet. An IP address has two parts: the identifier of a particular network on the Internet and an identifier of the particular device (which can be a server or a workstation) within that network. Each device must know its own IP address and the IP address of the device with which it needs to communicate (source and destination). To communicate on the Internet, every organization must have at least one valid Internet IP address. This unique network number is included in any packet sent out of the network onto the Internet. In addition to the network address or number, information is needed about which specific machine or host in a network is sending or receiving a message. So the IP address needs both the unique network number and a host number (which is unique within the network). Read the full definition of IP address is on Whatis.com.

IP Address Classes and Their Formats

Since networks vary in size, there are four different address formats or classes to consider when applying to NIC for a network number:
Class A addresses are for large networks with many devices.
Class B addresses are for medium-sized networks.
Class C addresses are for small networks (fewer than 256 devices).
Class D addresses are multicast addresses.
The first few bits of each IP address indicate which of the address class formats it is using. The address structures look like this:

Class A0 Network (7 bits) Local address (24 bits)


Class B10 Network (14 bits) Local address (16 bits)


Class C110 Network (21 bits) Local address (8 bits)


Class D1110 Multicast address (28 bits)


The IP address is usually expressed as four decimal numbers, each representing eight bits, separated by periods. This is sometimes known as the dot address and, more technically, as dotted quad notation. For Class A IP addresses, the numbers would represent "network.local.local.local"; for a Class C IP address, they would represent "network.network.network.local". The number version of the IP address can (and usually is) represented by a name or series of names called the domain name.

The Internet's explosive growth makes it likely that, without some new architecture, the number of possible network addresses using the scheme above would soon be used up (at least, for Class C network addresses). However, a new IP version, IPv6, expands the size of the IP address to 128 bits, which will accommodate a large growth in the number of network addresses. For hosts still using IPv4, the use of subnets in the host or local part of the IP address will help reduce new applications for network numbers. In addition, most sites on today's mostly IPv4 Internet have gotten around the Class C network address limitation by using the Classless Inter-Domain Routing (CIDR) scheme for address notation.

The Network Part of the IP Address

The Internet is really the interconnection of many individual networks (it's sometimes referred to as an internetwork). So the Internet Protocol (IP) is basically the set of rules for one network communicating with any other (or occasionally, for broadcast messages, all other networks). Each network must know its own address on the Internet and that of any other networks with which it communicates. To be part of the Internet, an organization needs an Internet network number, which it can request from the Network Information Center (NIC). This unique network number is included in any packet sent out of the network onto the Internet.

IP address ?

IP address




- This definition is based on Internet Protocol Version 4. See Internet Protocol Version 6 (IPv6) for a description of the newer 128-bit IP address. Note that the system of IP address classes described here, while forming the basis for IP address assignment, is generally bypassed today by use of Classless Inter-Domain Routing (CIDR) addressing.
In the most widely installed level of the Internet Protocol (IP) today, an IP address is a 32-bit number that identifies each sender or receiver of information that is sent in packets across the Internet. When you request an HTML page or send e-mail, the Internet Protocol part of TCP/IP includes your IP address in the message (actually, in each of the packets if more than one is required) and sends it to the IP address that is obtained by looking up the domain name in the Uniform Resource Locator you requested or in the e-mail address you're sending a note to. At the other end, the recipient can see the IP address of the Web page requestor or the e-mail sender and can respond by sending another message using the IP address it received.

An IP address has two parts: the identifier of a particular network on the Internet and an identifier of the particular device (which can be a server or a workstation) within that network. On the Internet itself - that is, between the router that move packets from one point to another along the route - only the network part of the address is looked at.

Domain ?

domain name.

In general, a domain is an area of control or a sphere of knowledge.

1) In computing and telecommunication in general, a domain is a sphere of knowledge identified by a name. Typically, the knowledge is a collection of facts about some program entities or a number of network points or addresses.

2) On the Internet, a domain consists of a set of network addresses. This domain is organized in levels. The top level identifies geographic or purpose commonality (for example, the nation that the domain covers or a category such as "commercial"). The second level identifies a unique place within the top level domain and is, in fact, equivalent to a unique address on the Internet (an IP address). Lower levels of domain may also be used.

Strictly speaking, in the Internet's domain name system (DNS), a domain is a name with which name server records are associated that describe subdomains or host. For example, "whatis.com" could be a domain with records for "www.whatis.com" and "www1.whatis.com," and so forth.

3) In Windows NT and Windows 2000, a domain is a set of network resources (applications, printers, and so forth) for a group of users. The user need only to log in to the domain to gain access to the resources, which may be located on a number of different servers in the network.

Cross-domain applicability versus domain-specific resolution

Cross-domain applicability versus domain-specific resolution
A fundamental conflict underlies the current deliberations of diverse scholarly communities; namely the contrasting needs for an element set capable of adequately describing 'my' subject (whatever that may be) and an element set capable of providing inter-disciplinary interoperability.

Every addition of a discipline/interpretation/subject-specific element, SCHEME or TYPE to the Core serves to make it more effective within the discipline making the change, and consequently less effective everywhere else. A narrow line must be steered between the excesses of either approach, as we neither want a non-interoperable catalogue nor one too generalised to be of use to anyone.

Whilst it rapidly became clear that the implementation of 'pure' Dublin Core (Miller and Gill 1997), without any element qualifiers whatsoever, would result in a core unsuitable for use across the humanities, there is the ever-present danger that creation of an implementation too reliant upon detailed qualification and sub-qualification will prove equally unsuitable, for exactly the opposite reasons.
