The beneficial IPv6
IPv6 connectivity serves the purpose like a gadget with an automobile to connect things together. Unlike IPv4, IPv6 has an increased number of IT addresses and surely, this is not the only advantage of IPv6. As it’s World IPv6 Day, we are going to introduce you with six more advantages of IPv6, so that you start consider using or moving to IPv6 for all of your software, hardware and other services.
1. Well-organized routing
By making routing more effective and hierarchic, IPv6 connectivity also reduces the size of routing tables. ISPs (Internet Service Provider) can aggregate the prefixes of their customers’ networks in to a unit prefix and declare this unit prefix to the IPv6 Internet, when IPv6 permits it to do so. In summation to IPv6 networks, rather than handling the atomization through router, it is handled by source device, using a communications protocol for finding path’s maximum transmission unit (MTU).
2. Proficient packet handling
The process of packet processing has been made more efficient by using IPv6’s modified header. Unlike IPv4, IPv6 connectivity bears no IP-level confirmation, so there’s no need to calculate checksum at every router hop. Most of the link-layer technologies consist of capabilities regarding verification, and error-control ability and that’s what helps in getting rid of IP-level verification. In summation, the transport layers which covers end-to-end connection, have a verification method which helps detecting errors.
3. More ordered data flow
Multicast is supported by IPv6 instead of broadcast. By saving bandwidth of network, multicast permits bandwidth-intensive packet to flow like multimedia streams, multiple destinations at a time. Hosts which are not interested, must not process multicast packets. For identifying packets that belong to the same flow, IPv6 has introduced a new branch, which is called as Flow Label.
4. Easy network structure
One of the built in features of IPv6 connectivity is to automatically configure addresses. A prefix of the local link will be sent by a router in its advertisements. By supplying link-layer (MAC), an IP address can be generated by the host, where, the 64-bits of the local link prefix has been converted into EUI (Extended Universal Identifier).
5. Compatibility and extendibility
New and valuable services are enabled, by annihilating NAT (Network Address Translation), and thus genuine end-to-end connection at the IP layer is furbished up. To make VoIP and QoS (Quality of Service) rich, peer-to-peer networks are established which are easier to build and sustain.
6. Better security
IPv6 is strengthened by IPSec because it provides security, reliability and validation of data. Packets of IPv4 ICMP are vulnerable to malwares so large firewalls often block them. But when IPSec is applied to ICMPv6 (the Internet Control Message Protocol’s application to IPv6), the data may be permitted as it becomes more secure.
