Each device connected to the Internet has a unique IP address which other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as 192.168.1.1 (in IPv4), or more complex newer alphanumeric IP addresses such as 2400:cb00:2048:1::c629:d7a2 (in IPv6).
13/07/2020 · IPv4 is 32-Bit IP address whereas IPv6 is a 128-Bit IP address. IPv4 is a numeric addressing method whereas IPv6 is an alphanumeric addressing method. IPv4 binary bits are separated by a dot(.) whereas IPv6 binary bits are separated by a colon(:). IPv4 offers 12 header fields whereas IPv6 offers 8 header fields. 3/11/2019 · Under the IPv6 protocol, domain names like noip.com are changed into IP addresses via DNS as usual, but instead of the IPv4 DNS record type A, IPv6 uses record type AAAA, often referred to as “Quad-A.” Because the adoption of IPv6 has been slow, many domains have both IPv4 and IPv6 addresses. An example for google.com can be found below: The IPv4 to IPv6 Conversion tool helps you see how your IPv4 address would be represented in the new IPv6 protocol. This can aid network administrators who are migrating IPv4 to IPv6 networks and wish to preserve IPv4 addressing for compatibility and/or tracking purposes. For example if your IPv4 IP is 209.173.53.167 the valid IPv6 version will be 0:0:0:0:0:ffff:d1ad:35a7 Get IPv4 addresses from Dns.GetHostEntry() Ask Question Asked 11 years ago.

14/10/2011 · When a translation of domain name is requested, if Local DNS name server does not have a record of the certain domain, it sends a request to one of the 13 Root DNS Servers, located worldwide. The root DNS server then contacts the corresponding TLD DNS server (org, com, etc) for cached records of the given domain name. Then the TLD DNS server contacts Authoritative DNS server, which contains 3/06/2016 · It is intended for testing IPv6-only devices when you only have IPv4 connectivity to the Internet, and only works with the included DNS64 (IPv6-only devices connected to it cannot use Google Public DNS directly, although you can configure the MacOS X system to use 8.8.8.8 and 8.8.4.4). dns: list of ip addresses : no (none) Supplement DHCP-assigned DNS server(s), or use only these if peerdns is 0 : peerdns: boolean : no : 1: Use DHCP-provided DNS server(s) defaultroute: boolean : no : 1: Whether to create a default route via the received gateway : customroutes: string : no (none) Space-separated list of additional routes to In IPv4, DNS was significant for Internet usability because people found it difficult to remember 12-digit IP addresses. With the transition to IPv6, DNS becomes critical, because no-one can remember a 128-bit hexadecimal address. As the Internet shifts from IPv4 to IPv6, hostnames stay the same.
