IPv4 vs IPv6 – What’s the Distinction and Which Is Higher?

The web is massive with completely different streams of communication. An IP deal with is without doubt one of the methods gadgets talk or connect with a community by means of the IP protocol. An IP (Web Protocol) deal with, additionally referred to as an Web deal with or IP quantity, is an identifier or label given to any gadget linked to a community. The IP protocol is used to speak between the gadget and the pc community. The identifier or label could be numerical or alphanumeric.  

The particular perform of an IP deal with is to establish a particular gadget to a specific community. The IP deal with additionally features to specify the technical format of addressing the gadget to the community. Combining IP with TCP (Transmission Management Protocol) helps for higher communication and connection between a particular gadget and a community, which permits the event of the digital connection between the sender and the receiver. Nevertheless, there are two variations of IP; these variations decide the options, pace, and routing effectivity that retains your web working.

What’s IPv4?

IPv4, Web Protocol model 4, is the fourth Web Protocol model. IPv4 can be the primary model used on SATNET and ARPANET manufacturing. IPv4 has been in existence since 1983, and up till now, it has been used for routing web visitors. Regardless of newer improvement in web protocols, IPv4 remains to be related in its utilization.

IPv4 is the expertise used to attach gadgets to the web and a singular numerical IP deal with to permit a tool to freely entry the web. The IPv4 format is in a dotted-decimal or dotted quad, x.x.x.x. Nevertheless, every x ought to have a price between 0 and 225. An instance of an IPv4 deal with is The communication between gadgets is finished when the info packet is transferred by way of the community utilizing IP addresses.

One of many options of IPv4 is that it makes use of 32-bit for its web addresses. The deal with house of IPv4 makes use of a singular deal with of 4,294,967,296 (232) with the reservation of enormous blocks for distinctive networking. The variety of particular person hosts within the deal with house is restricted to 232, which is about 4.3 billion ipv4 addresses for folks to make use of.

Components of Web Protocol Model 4

  1. Community Half

    This half within the IPv4 demonstrates the particular vary assigned to a community. This a part of the IPv4 deal with concurrently identifies the given community group.

  2. Host Half

    The IPv4 host half is assigned to each host, and it’s answerable for figuring out the machine in your community. In different phrases, the community half stays the identical on every host on the community however varies if it’s the host half.

  3. Subnet Half

    The subnet half in IPv4 is the discretional half. Subnet numbers are assigned to native networks with large numbers of hosts. Earlier than assigning numbers, they’re first divided into subnets after which given subnet numbers. 

Options of IPv4

  • IPv4 has 32-Bit IP addresses.

  • The IP deal with of IPv4 is numeric. 

  • A dot separates the 32-bit IP deal with.

  • The size of the IPv4 header file is 20, and the variety of its header fields is 12.

  • The IPv4 fashion of addresses has broadcast, unicast and multicast.

  • IPv4 helps and makes use of VLSM (Digital Size Subnet Masks)

  • When mapping MAC addresses, IPv4 makes use of Put up Handle Decision Protocol.

  • Customers strategy DHCS (Dynamic Host Configuration server) every time they wish to connect with a community.

  • IPv4 networks are designed manually or with DHCP. 

  • IPv4 packet fragmentation permits inflicting host and routers.

  • In IPv4, RIP can be utilized as a routing protocol, so long as the routed daemon helps them.

Execs of IPv4

  • With regards to internet development, IPv4 hinders using internet achieve for brand spanking new customers and limits its internet development for current customers. 

What’s IPv6?

Touch screen with IPv6

IP (Web Protocol) model 6, often known as IPng (Web Protocol subsequent era), is the next-generation Web Protocol deal with. IPv6 was designed to enrich or exchange IPv4. IPv6 is a model of web protocol that enables communication between gadgets and the web. Web Engineering Activity Power (IETF) designed this web protocol model to usurp IPv4 in December 1998. The first objective of growing IPv6 is to create extra deal with areas for the rising variety of web customers; it additionally comes with different options that surpass the IPv4.

Whether or not it’s a pc, IoT sensor, house automation gadget, cell phone, or different {hardware}, each gadget wants an IP deal with to hook up with the web and talk with different gadgets. With IPv6, every gadget has a singular public IP deal with, as a result of the protocol can accommodate all linked gadgets within the international world. The model 6 IP has an alphanumeric addressing system with eight teams of 4 hexadecimal digits. An instance of this deal with is 2001:0db8:85a3:0000:0000:8a2e:0370:7334. IPv6 has a 128-bit deal with house that enables 340 undecillion distinctive deal with areas to speak on the web. With IPv6, IP addresses are limitless, because it helps a theoretical most of 340, 282, 366, 920, 938, 463, 374, 607, 431, 768, 211, 456.

Sorts of IPv6 Addresses

Three varieties of IPv6 addresses are:

  1. Unicast Handle

A unicast deal with helps establish the particular and distinctive node on a community. Whether or not it’s a single receiver or a single sender.

  1. Multicast Handle

A multicast deal with is a particular IP deal with labeling a community location used to multicast knowledge packets inside a community. They’re used because the vacation spot of a datagram, and it additionally identifies a bunch of IP gadgets.

  1. Anycast Handle

Anycast addresses are assigned to a set of interfaces that belong to completely different nodes.

 Execs of IPv6

  • IPv6 is dependable, with higher routing effectivity.
  • It has sooner speeds because it has higher multicast routing that enables bandwidth-intensive packet flows to be despatched to completely different locations concurrently.
  • IPv6 has a extra simple header format.
  • IPv6 has higher privateness assist and built-in authentication.
  • IPv6 has extra rising nodes within the international community
  • The Web Protocol Safety of IPv6 supplies for knowledge integrity and confidentiality.
  • Configuration capabilities in IPv6 permits {hardware} to assign a number of IP addresses to the identical gadget robotically.

Cons of IPv6

  • It’s difficult to transform to maneuver to IPv6 as IPv4 is broadly in use.
  • IPv6 will want an intermediate expertise to speak with IPv4, as they can not talk straight.

IPv4 and IPv6, which is best?


After contemplating the variations between IPv4 and IPv6, the next will clarify which IP deal with model is best.

  1. Efficiency: Expanse of IP Handle

The efficiency of those IP variations will depend on their deal with measurement. For instance, IPv4 has 32-bit deal with house, whereas IPv6 has 128-bit hexadecimal deal with house. IPv6 has a bigger deal with house that enables for a easy header and accommodates significantly bigger deal with calls for with simplified routing.

  1. IP Header Format: Decreased Header Bandwidth

An IPv6 deal with has prolonged headers 4 instances bigger than IPv4 addresses. This added characteristic within the IPv6 deal with helps scale back the overhead of packet processing and header bandwidth, making the connection a lot sooner.

  1. Community Safety: Extra Safe and Confidential

With regards to community safety in IPv6, IPSec is required for its operation whereas it’s elective or comes with a value in IPv4. This characteristic in IPv6 helps for knowledge consistency, higher safety, and confidentiality in your community.

  1. Community Safety: Quicker Pace and Lack of NAT

IPv6 is quicker than IPv4 in community gadgets as a result of it lacks network-address translation (NAT). Utilizing IPv6 is a better option for those who require excessive pace for his or her community processing.


Utilizing IP model 6 is advisable once you want optimum routing effectivity on your explicit community software. Due to the almost limitless deal with house provided by IPv6, each gadget in your community can have a singular public IP deal with. Then again, IPv4 and IPv6 are usually not appropriate to begin. You’ll need middleman expertise to make sure compatibility and performance between the 2 protocols.
