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


The web is huge with other streams of communique. An IP handle is among the techniques units keep up a correspondence or hook up with a community throughout the IP protocol. An IP (Web Protocol) handle, also known as an Web handle or IP quantity, is an identifier or label given to any software hooked up to a community. The IP protocol is used to keep up a correspondence between the software and the pc community. The identifier or label will also be numerical or alphanumeric.  

The particular serve as of an IP handle is to spot a selected software to a selected community. The IP handle additionally purposes to specify the technical structure of addressing the software to the community. Combining IP with TCP (Transmission Keep watch over Protocol) is helping for higher communique and connection between a selected software and a community, which permits the advance of the digital connection between the sender and the receiver. On the other hand, there are two variations of IP; those variations decide the options, velocity, and routing potency that assists in keeping your web running.

What’s IPv4?

IPv4 futuristic image

IPv4, Web Protocol model 4, is the fourth Web Protocol model. IPv4 may be the primary model used on SATNET and ARPANET manufacturing. IPv4 has been in lifestyles since 1983, and up till now, it’s been used for routing web visitors. In spite of more moderen construction in web protocols, IPv4 remains to be related in its utilization.

IPv4 is the generation used to glue units to the web and a singular numerical IP handle to permit a tool to freely get entry to the web. The IPv4 structure is in a dotted-decimal or dotted quad, x.x.x.x. On the other hand, each and every x must have a price between 0 and 225. An instance of an IPv4 handle is The communique between units is finished when the knowledge packet is transferred by means of the community the use of IP addresses.

Some of the options of IPv4 is that it makes use of 32-bit for its web addresses. The handle house of IPv4 makes use of a singular handle of four,294,967,296 (232) with the reservation of enormous blocks for remarkable networking. The selection of person hosts within the handle house is restricted to 232, which is ready 4.3 billion ipv4 addresses for folks to make use of.

Portions of Web Protocol Model 4

  1. Community Phase

    This phase within the IPv4 demonstrates the particular vary assigned to a community. This a part of the IPv4 handle concurrently identifies the given community team.

  2. Host Phase

    The IPv4 host phase is assigned to each and every host, and it’s accountable for figuring out the device to your community. In different phrases, the community phase stays the similar on each and every host at the community however varies if it’s the host part.

  3. Subnet Phase

    The subnet phase in IPv4 is the discretional phase. Subnet numbers are assigned to native networks with huge 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 handle of IPv4 is numeric. 

  • A dot separates the 32-bit IP handle.

  • The period of the IPv4 header report is 20, and the selection of its header fields is 12.

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

  • When mapping MAC addresses, IPv4 makes use of Put up Deal with Solution Protocol.

  • Customers manner DHCS (Dynamic Host Configuration server) on every occasion they need to hook up 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

  • Some of the advantages of IPv4 is that it’s protected, and privateness is confident. IPv4 will also be encrypted, permitting it to stick in keeping with ip safety and privateness developments.

  • The allocation of networks in IPV4 is strong, with about 85,000 sensible routers.

  • IPv4 lets you attach a couple of units throughout an oversized community with out the use of NAT.

  • IPv4 supplies high quality communique carrier and economical wisdom switch.

  • IPV4 addresses permit for very best redefined encoding.

  • IPv4 permits for collective addressing because the routing is scalable and economical. 

  • IPv4 allows community knowledge communique in multicast organizations.

Cons of IPv4

  • Web routing is useless in IPv4.

  • It’s tough to reinforce positive new programs. If any supported function is added, it leads to top overhead because it hinders flexibility for attachment.

  • IPv4 is just a little dear because it has top machine control costs.

  • IPv4 is complicated, sluggish, and susceptible to mistakes.

  • IPv4 is labor-intensive, and its security measures are elective.

  • Relating to internet expansion, IPv4 hinders using internet achieve for brand new customers and boundaries its internet expansion for current customers. 

What’s IPv6?

Touch screen with IPv6

IP (Web Protocol) model 6, sometimes called IPng (Web Protocol subsequent technology), is the next-generation Web Protocol handle. IPv6 used to be designed to counterpoint or exchange IPv4. IPv6 is a model of web protocol that permits communique between units and the web. Web Engineering Job Power (IETF) designed this web protocol model to usurp IPv4 in December 1998. The main goal of creating IPv6 is to create extra handle areas for the rising selection of web customers; it additionally comes with different options that surpass the IPv4.

Whether or not it’s a pc, IoT sensor, house automation software, cell phone, or different {hardware}, each and every software wishes an IP handle to hook up with the web and keep up a correspondence with different units. With IPv6, each and every software has a singular public IP handle, for the reason that protocol can accommodate all hooked up units within the international international. The model 6 IP has an alphanumeric addressing machine with 8 teams of 4 hexadecimal digits. An instance of this handle is 2001:0db8:85a3:0000:0000:8a2e:0370:7334. IPv6 has a 128-bit handle house that permits 340 undecillion distinctive handle areas to keep up a correspondence 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.

Varieties of IPv6 Addresses

3 varieties of IPv6 addresses are:

  1. Unicast Deal with

A unicast handle is helping establish the particular and distinctive node on a community. Whether or not this can be a unmarried receiver or a unmarried sender.

  1. Multicast Deal with

A multicast handle is a selected IP handle 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 gaggle of IP units.

  1. Anycast Deal with

Anycast addresses are assigned to a suite of interfaces that belong to other nodes.

 Execs of IPv6

  • IPv6 is dependable, with higher routing potency.
  • It has sooner speeds because it has higher multicast routing that permits bandwidth-intensive packet flows to be despatched to other locations concurrently.
  • IPv6 has a easier header structure.
  • IPv6 has higher privateness reinforce and integrated authentication.
  • IPv6 has extra rising nodes within the international community
  • The Web Protocol Safety of IPv6 supplies for knowledge integrity and confidentiality.
  • Configuration features in IPv6 allows {hardware} to assign a couple of IP addresses to the similar software mechanically.

Cons of IPv6

  • It’s difficult to transform to transport to IPv6 as IPv4 is broadly in use.
  • IPv6 will want an intermediate generation to keep up a correspondence with IPv4, as they can not keep up a correspondence immediately.

IPv4 and IPv6, which is best?


After bearing in mind the variations between IPv4 and IPv6, the next will provide an explanation for which IP handle model is best.

  1. Efficiency: Expanse of IP Deal with

The efficiency of those IP variations depends upon their handle dimension. For instance, IPv4 has 32-bit handle house, whilst IPv6 has 128-bit hexadecimal handle house. IPv6 has a bigger handle house that permits for a easy header and comprises significantly better handle calls for with simplified routing.

  1. IP Header Structure: Diminished Header Bandwidth

An IPv6 handle has prolonged headers 4 instances better than IPv4 addresses. This added function within the IPv6 handle is helping cut back the overhead of packet processing and header bandwidth, making the relationship a lot sooner.

  1. Community Safety: Extra Safe and Confidential

Relating to community safety in IPv6, IPSec is needed for its operation whilst it’s not obligatory or comes with a price in IPv4. This option in IPv6 is helping for knowledge consistency, higher safety, and confidentiality on your community.

  1. Community Safety: Sooner Velocity and Loss of NAT

IPv6 is quicker than IPv4 in community units as it lacks network-address translation (NAT). The use of IPv6 is a better option for those that require top velocity for his or her community processing.


The use of IP model 6 is beneficial when you wish to have optimum routing potency on your specific community software. As a result of the just about limitless handle house presented through IPv6, each and every software to your community may have a singular public IP handle. Then again, IPv4 and IPv6 aren’t appropriate to begin. You’re going to want middleman generation to make sure compatibility and capability between the 2 protocols. These days, IPv4 dominates the general public web house and is broadly used for such things as server cluster webhosting and on devoted servers.
