How To Find Your IP Address DNS Address IPv4 IPv6

Larger address area :

The main feature of IPv6 that’s driving adoption nowadays is that the larger address  space:  addresses in IPv6 square measure 128 bits long versus thirty two bits in IPv4.
The larger address area avoids the potential exhaustion of the IPv4 address area while not the necessity for network address translation (NAT) and alternative devices that break the end-to-end nature of web traffic. NAT should still be necessary in rare cases, however web engineers acknowledge that it’ll be troublesome in IPv6 and try to avoid it whenever potential. It conjointly makes administration of medium and enormous networks less complicated, by avoiding the necessity for advanced subnetting schemes. Subnetting can, ideally, revert to its purpose of logical segmentation of AN science network for optimum routing and access.
The drawback of the massive address size is that IPv6 carries some information measure overhead over IPv4, {which may|which will} hurt regions wherever information measure is restricted (header compression can typically be accustomed alleviate this problem). IPv6 addresses square measure tougher to memorise than IPv4 addresses, though even IPv4 addresses square measure abundant tougher to memorise than name System (DNS) names. DNS protocols are changed to support IPv6 also as IPv4.

homeless motorcar configuration of hosts :

IPv6 hosts are often designed mechanically once connected to a routed IPv6 network. once 1st connected to a network, a number sends a link-local multicast request for its configuration parameters; if designed befittingly, routers reply to such missive of invitation with a router publicity packet that contains network-layer configuration parameters.
If IPv6 autoconfiguration isn’t appropriate, a number will use stateful autoconfiguration (DHCPv6) or be designed manually. homeless autoconfiguration is merely appropriate for  hosts:  routers should be designed manually or by alternative suggests that

IPv6 scope :

IPv6 defines three unicast address  scopes: world, site, and link.
Site-local addresses square measure non-link-local addresses that square measure valid among the scope of AN administratively-defined website and can’t be exported on the far side it.
Companion IPv6 specifications any outline that solely link-local addresses are often used once generating ICMP send Messages [ND] and as next-hop addresses in most routing protocols.
These restrictions do imply that AN IPv6 router should have a link-local next-hop address for all directly connected routes (routes that the given router and therefore the next-hop router share a typical subnet prefix).
