what is easier to work with ipv4 or ipv6

What is IP?

An IP (Internet Protocol) accost is a numerical label assigned to each device connected to a computer network that uses the IP protocol for advice. An IP accost acts as an identifier for a specific device on a particular network. The IP address is also called an IP number or Net address.

IP accost specifies the technical format of the addressing and packets scheme. Well-nigh networks combine IP with a TCP (Transmission Control Protocol). It also allows developing a virtual connectedness between a destination and a source.

Now in this IPv4 and IPv6 departure tutorial, we will learn What is IPv4 and IPv6?

What is IPv4?

IPv4 is an IP version widely used to identify devices on a network using an addressing arrangement. It was the first version of IP deployed for product in the ARPANET in 1983. It uses a 32-bit address scheme to store ii^32 addresses which is more than than iv billion addresses. It is considered the master Internet Protocol and carries 94% of Internet traffic.

What is IPv6?

IPv6 is the most recent version of the Cyberspace Protocol. This new IP address version is being deployed to fulfill the need for more Internet addresses. It was aimed to resolve issues that are associated with IPv4. With 128-bit address space, it allows 340 undecillion unique address infinite. IPv6 is besides called IPng (Internet Protocol next generation).

Net Engineer Taskforce initiated information technology in early on 1994. The design and development of that suite are now called IPv6.

Key DIFFERENCE

• IPv4 is 32-Bit IP accost whereas IPv6 is a 128-Bit IP address.
• IPv4 is a numeric addressing method whereas IPv6 is an alphanumeric addressing method.
• IPv4 binary $.25 are separated by a dot(.) whereas IPv6 binary $.25 are separated by a colon(:).
• IPv4 offers 12 header fields whereas IPv6 offers 8 header fields.
• IPv4 supports broadcast whereas IPv6 doesn't support circulate.
• IPv4 has checksum fields while IPv6 doesn't accept checksum fields
• When nosotros compare IPv4 and IPv6, IPv4 supports VLSM (Variable Length Subnet Mask) whereas IPv6 doesn't support VLSM.
• IPv4 uses ARP (Address Resolution Protocol) to map to MAC address whereas IPv6 uses NDP (Neighbour Discovery Protocol) to map to MAC address.

Features of IPv4

Following are the features of IPv4:

• Connectionless Protocol
• Allow creating a elementary virtual communication layer over diversified devices
• Information technology requires less retentivity, and ease of remembering addresses
• Already supported protocol past millions of devices
• Offers video libraries and conferences

Features of IPv6

Here are the features of IPv6:

• Hierarchical addressing and routing infrastructure
• Stateful and Stateless configuration
• Support for quality of service (QoS)
• An ideal protocol for neighboring node interaction

IPv4 vs IPv6

Differences Between IPv4 and IPv6 Addresses

Here is the primary divergence between IPv4 and IPv6:

Basis for differences	IPv4	IPv6
Size of IP accost	IPv4 is a 32-Scrap IP Address.	IPv6 is 128 Bit IP Address.
Addressing method	IPv4 is a numeric address, and its binary bits are separated by a dot (.)	IPv6 is an alphanumeric accost whose binary bits are separated by a colon (:). Information technology also contains hexadecimal.
Number of header fields	12	viii
Length of header filed	20	40
Checksum	Has checksum fields	Does not have checksum fields
Example	12.244.233.165	2001:0db8:0000:0000:0000:ff00:0042:7879
Type of Addresses	Unicast, circulate, and multicast.	Unicast, multicast, and anycast.
Number of classes	IPv4 offers five unlike classes of IP Address. Class A to E.	lPv6 allows storing an unlimited number of IP Accost.
Configuration	You have to configure a newly installed arrangement before it can communicate with other systems.	In IPv6, the configuration is optional, depending upon on functions needed.
VLSM support	IPv4 back up VLSM (Variable Length Subnet mask).	IPv6 does not offer support for VLSM.
Fragmentation	Fragmentation is done by sending and forwarding routes.	Fragmentation is done past the sender.
Routing Information Protocol (RIP)	RIP is a routing protocol supported by the routed daemon.	RIP does non support IPv6. It uses static routes.
Network Configuration	Networks demand to be configured either manually or with DHCP. IPv4 had several overlays to handle Internet growth, which require more maintenance efforts.	IPv6 back up autoconfiguration capabilities.
Best feature	Widespread utilise of NAT (Network accost translation) devices which allows single NAT address tin can mask thousands of not-routable addresses, making terminate-to-stop integrity achievable.	It allows direct addressing because of vast address Space.
Address Mask	Utilize for the designated network from host portion.	Not used.
SNMP	SNMP is a protocol used for system management.	SNMP does not back up IPv6.
Mobility & Interoperability	Relatively constrained network topologies to which motion restrict mobility and interoperability capabilities.	IPv6 provides interoperability and mobility capabilities which are embedded in network devices.
Security	Security is dependent on applications – IPv4 was not designed with security in mind.	IPSec(Internet Protocol Security) is built into the IPv6 protocol, usable with a proper key infrastructure.
Packet size	Packet size 576 bytes required, fragmentation optional	1208 bytes required without fragmentation
Packet fragmentation	Allows from routers and sending host	Sending hosts but
Packet header	Does not place package period for QoS handling which includes checksum options.	Packet head contains Flow Label field that specifies bundle flow for QoS handling
DNS records	Address (A) records, maps hostnames	Accost (AAAA) records, maps hostnames
Address configuration	Manual or via DHCP	Stateless accost autoconfiguration using Internet Command Message Protocol version vi (ICMPv6) or DHCPv6
IP to MAC resolution	Broadcast ARP	Multicast Neighbor Solicitation
Local subnet Group management	Internet Grouping Management Protocol GMP)	Multicast Listener Discovery (MLD)
Optional Fields	Has Optional Fields	Does non have optional fields. Only Extension headers are bachelor.
IPSec	Internet Protocol Security (IPSec) apropos network security is optional	Cyberspace Protocol Security (IPSec) Concerning network security is mandatory
Dynamic host configuration Server	Clients have approach DHCS (Dynamic Host Configuration server) whenever they want to connect to a network.	A Client does not have to approach whatsoever such server as they are given permanent addresses.
Mapping	Uses ARP(Accost Resolution Protocol) to map to MAC accost	Uses NDP(Neighbour Discovery Protocol) to map to MAC address
Combability with mobile devices	IPv4 address uses the dot-decimal note. That's why information technology is not suitable for mobile networks.	IPv6 address is represented in hexadecimal, colon- separated annotation. IPv6 is better suited to mobile networks.

IPv4 and IPv6 cannot communicate with other but can exist together on the aforementioned network. This is known as Dual Stack.

Summary

What is the Difference Between IPv4 and IPv6?

IPv4 & IPv6 are both IP addresses that are binary numbers. IPv4 is a 32-bit binary number, and IPv6 is a 128-bit binary number address. IPv4 addresses are separated past periods, while IPv6 addresses are separated past colons.

Both IP addresses are used to identify machines continued to a network. In principle, they are almost similar, but they are different in how they piece of work.

Is IPv4 or IPv6 better?

IPv4 is the fourth version of the Cyberspace Protocol (IP), while IPv6 is the near recent version of the Internet Protocol. Therefore, IPv6 is more advanced, secure, and faster compared to IPv4.
