Name resolution for IPv6 addresses can be static or dynamic. Just as with IPv4, resolution of static names to IPv6 addresses can be manually configured in the host configuration file. […]
IPv6 Address-Assignment Strategies – Internet Protocol Version 6 (IPv6) Design
Assignment of IPv6 addresses to a host can occur statically or dynamically. Static IPv6 address assignment involves manual configuration on the host’s configuration files. Dynamic IPv6 address assignment can be […]
DHCPv6 – Internet Protocol Version 6 (IPv6) Design
Dynamic Host Configuration Protocol version 6 (DHCPv6) is an updated version of DHCP that provides dynamic IP address assignment for IPv6 hosts. DHCPv6, described in RFC 3315, provides the same […]
RIPng – Internet Protocol Version 6 (IPv6) Design
RFC 2080 describes changes to RIP to support IPv6 networks, called Routing Information Protocol next generation (RIPng). RIP mechanisms remain the same. RIPng still has a 15-hop limit, counting to […]
IPv6 Addressing Design – Internet Protocol Version 6 (IPv6) Design
This section covers IPv6 design topics that a CCNP enterprise designer should be aware of: planning for IPv6 addressing, IPv6 route summarization, IPv6 address allocation, and IPv6 private addressing. Some […]
IPv6 Private Addressing – Internet Protocol Version 6 (IPv6) Design
IPv6 private addressing should be very limited compared to its use in IPv4. IPv6 private IP addresses are referred to as unique local addresses (ULAs) and use the prefix FC00::/7. […]
Whole IPv4 Address Linked to IPv6 – Internet Protocol Version 6 (IPv6) Design
Another method of IPv6 address allocation is to link a whole IPv4 address to the lowest significant bits of the IPv6 address. Table 2-11 shows an example using the same […]
IPv6 over IPv4 Tunneling Strategy – Internet Protocol Version 6 (IPv6) Design
In the IPv6 over IPv4 tunneling migration strategy, isolated IPv6-only networks are connected using IPv4 tunnels. With overlay tunnels, IPv6 packets are encapsulated within IPv4 packets so that they are […]
6RD Tunnels – Internet Protocol Version 6 (IPv6) Design
IPv6 Rapid Deployment (6RD) tunnels are an extension of 6to4 and allow a service provider to provide unicast IPv6 service to customers over its IPv4 network by using encapsulation of […]
DNS64 – Internet Protocol Version 6 (IPv6) Design
With DNS64, as defined in RFC 6147, when an IPv6 AAAA resource record (RR) is not available, DNS64 enables the DNS server to synthesize an AAAA record from an IPv4 […]
