RFC 8200 IPv6 Specification July 2017 The data transmission order for IPv6 is the same as for IPv4 as defined in Appendix B of [RFC791].Note: As this document obsoletes [], any document referenced in this document that includes pointers to RFC 2460 should be interpreted as referencing this document.

IPv6 is written in hexadecimal which uses the digits 0-9 and a-f. A hexadecimal digit represents 4 bits, or 16 decimal units. Each IPv6 address is represented by eight groups of four hexadecimal digits. These groups are separated by colons. An example may be: 2001:0db8:2231:aaec:0000:0000:4a4a:2100. Try practicing binary. IPv6 Ping. To diagnose basic network connectivity using IPv6 to the specified address, enter the following command: Router#ping ipv6 2001:db8::3/64 The following characters can be displayed as output when using PING in IPv6. Free tool to convert IPv4 address into 6to4 address and IPv4-mapped IPv6 address. Summarizing IPv6 prefixes is similar to IPv4 summarization, the big difference is that IPv6 uses 128 bit addresses compared to 32 bits for IPv4 and IPv6 uses hexadecimal addresses. In this lesson, I’ll explain how to create IPv6 summaries and we’ll walk through some examples together. Example 1. Let’s start with a simple example: Substitute Preferred DNS address in the command above with the actual preferred IPv4 or IPv6 DNS server address (see table below) you want to use for this network connection. For example: netsh interface ipv6 set dnsservers "Ethernet" static 2001:4860:4860:0:0:0:0:8888 primary RFC 8200 IPv6 Specification July 2017 The data transmission order for IPv6 is the same as for IPv4 as defined in Appendix B of [RFC791].Note: As this document obsoletes [], any document referenced in this document that includes pointers to RFC 2460 should be interpreted as referencing this document.

Subnet the following IP address for 2000 networks. Complete the table with the information for the first four newly created subnets. 10.0.0.0 New Subnet Mask: 255.255.224.0

The most obvious and recognizable difference between IPv4 and IPv6 is the IPv6 address. An IPv4 address is 32 bits and expressed in dotted-decimal notation, whereas an IPv6 address is 128 bits in length and written in hexadecimal.

The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. However, rather than being expressed in four octets like it is in IPv4, it is expressed as an integer between 1 through 128. For example: 2001:db8:abcd:0012::0/64 specifies a subnet with a range of IP addresses from: 2001:db8:abcd:0012: 0000:0000:0000:0000 - 2001:db8:abcd

2001-db8-a0b-12f0--1.ipv6-literal.net: subnet-level I: IPv4/IPv6 subnet calculator and hierarchical IPv6 addressing plan builder This is the online version of As part of our long term planning we have applied for an IPv6 address and were assigned 2001:db8:abcd::/48. We now need to allocate this across our enterprise. We have branches in most states, so we've decided to use Option B, giving us 16 sites, 16 sub-sites and 256 subnets per site.
