Guideline on MONIC IPv6

Domain Name “.mo” received an allocation of IPv6 IP address from the Internet Assigned Numbers Authority (IANA) and was officially on June 2014.

Public can now visit Macao Network Information Centre (MONIC) IPv6 website and related domain devices.

Q1 How to configure an IPv6 Domain Hosting (Host) and a Domain Name System (DNS) at the MONIC backstage?

A1 IPv6 format is fully supported by the MONIC backstage system, customer can input the hostname that supports an IPv6 format in the DNS, however customer can also direct input the IP address in an IPv6 format to the backstage of Host if they do not have any DNS. Wait until the system to synchronize, the domain name will then be connected to its corresponding IP address.

Configure DNS:

Login → Domain Management → My Domain → Domain Name System (DNS) → Add DNS → Save (System can run simultaneously within 5-15 minutes.)

Configure Host:

Login → Domain Management → My Domain → Domain Hosting (Host) → Input the Hostname and IP address → Save (System can run simultaneously within 5-15 minutes.)

Q2 Can the public explore once configured an IP address to IPv6 server at the MONIC backstage?

A2 Yes, the setting will be the same as IPv4, such as the AAAA record points to an IPv6 IP address directly.

E.g. Under the domain name, set hostname as www and its IP address as 2001:f90:2:8::5 (MONIC home page), after system runs simultaneously, public can enter in the search engine and go to MONIC main page.

Q3 How do I know if “My Devices” can support and configure IPv6?

A3 Please consult the devices supplier of your company for learning the backup situation of the related devices.

Q4 Which IP will normal user use when both IPv4 address and IPv6 address are set under the same Host?

A4 Situation 1 : If user’s computer and network can support both IPv4 & IPv6, without advanced configuration, the preference of the user’s computer will choose the IPv6 address automatically.

     Situation 2 : If user’s computer and network can only support IPv4 but not IPv6, then user’s computer will choose the IPv4 address and exclude the IPv6 address directly.

     Situation 3 : If user’s computer and network can support both IPv4 & IPv6, however the user set its own priority as IPv4, the preference of the user’s computer will then choose IPv4 address automatically.

II. About IPv6

Q1 What is an IP address?

A1 On Internet, an Internet Protocol Address is a numerical value for identifying an internet location, the abbreviation is IP Address and is classified into two main version: IP Version 4 (IPv4) and IP Version 6 (IPv6).

Q2 What is the definition of IPv4 and IPv6?

A2 The Internet Protocol used on the internet is classified into Version 4 & Version 6. IPv4 is the fourth version of the Internet Protocol, uses a 32- bit address scheme, divided into four parts by ".” and written in decimal (E.g. However, the rapid growth of the internet causes the depletion of IPv4 address, the Internet Engineering Task Force (IETF) then developed the sixth version of the Internet Protocol and the newest version is called IPv6. Compared with IPv4, the length of IPv6 address is longer, uses a 128-bit address scheme, divided by “:” with specifying hexadecimal notation (E.g. 3ffe:0507:0001::1).

Q3 What are the main advantages of IPv6?

A3 (1)More address space: IPv4 uses a 32-bit address scheme allowing for a total of 232 addresses; while IPv6 uses a 128-bit address allowing for a total of 2128 addresses.

     (2)More secure: Using IPv6 internet reinforces the internet security by enabling users to encrypt data in network layer and validate an IP.

Q4 How can I get an IPv6 address?

A4 Normal business or personal users, please consult your own Internet Service Provider (ISP).
