Domain Names - Technical Information |
For reference we have included a brief description of the editable/updateable parts of a domain name that Pixelism as the Administrators & Technical contacts for a domain manage or adjust if and when required. For example to alter the MX Record to point to an internal mail server of a company network or alter the DNS Records to point a domain name to new servers.
Each domain name has at least two nameservers so that if one should fail, or is busy, the other nameserver can take over and host your site. To change your hosting provider either to us or away from our services, you need to change your domain name's nameserver records. An A record or address record maps a hostname to a 32-bit IPv4 address. An AAAA record or IPv6 address record maps a hostname to a 128-bit IPv6 address. A CNAME record or canonical name record is an alias of one name to another. The A record that the alias is pointing to can be either local or remote - on a foreign name server. This is useful when running multiple services (like an FTP and a webserver) from a single IP address. Each service can then have its own entry in DNS (like ftp.example.com and www.example.com.) An MX record or mail exchange record maps a domain name to a list of mail exchange servers for that domain.
IPv6: Internet Protocol version 6 (IPv6) is a network layer protocol for packet-switched internetworks. It is designated as the successor of IPv4, the current version of the Internet Protocol, for general use on the Internet. The main improvement brought by IPv6 (Internet Protocol version 6) is the increase in the number of addresses available for networked devices, allowing, for example, each mobile phone and mobile electronic device to have its own address. IPv4 supports 232 (about 4.3 billion) addresses, which is inadequate for giving even one address to every living person, let alone supporting embedded and portable devices. IPv6, however, supports 2128 addresses; this is approximately 5×1028 addresses for each of the roughly 6.5 billion people alive today. With such a large address space available, IPv6 nodes can have as many universally scoped addresses as they need, and network address translation is not required. |
