When IPv4 address was invented, it wasn’t expected that using the web would become very popular also it might have countless devices with such IP addresses. The IETF defined IPv4 addresses in RFC 791 printed almost 30 years ago. The very first style of IPv4 doesn’t expect the development from the internet which produced many issues, which demonstrated IPv4 have to be altered. Over time, IPv4 has updated to deal with new challenges. However, still, some major issues like lack of IPv4 Address, Finish to Finish Connectivity, QoS, etc which we the following.
Lack of IPv4 Addresses
The IPv4 addresses possess a 32-bit address space. The 32-bit address space is further split into A, B, C, D and E classes. These classes possess a small group of unique public IP addresses that is about 4 billion. While there’s, the growing quantity of new IP-enabled devices, always-on connections, and also the potential development of less-developed regions have elevated the requirement for more addresses cause lack of IPv4 addresses. Because the exhaustion and lack of IPv4 addresses recognized, engineers ideas some solutions which aren’t permanent but just like a workaround to temporary or temporary solutions is CIDR, NAT, and Addressing. We’ll discuss these solutions in details in coming articles.
Security Related Issues
When I write earlier that IP version 4 addresses were printed almost 30 years ago and also the present network security issues weren’t expected in those days. So Security is yet another big aspect where IP version 4 were built with a break the rules. Ip Address Security (IP sec) is really a protocol suite which helps network security. Ip Address Security (IP sec) provides to safeguard IP version 4 packets, but it’s not built-in.
Address configuration related issues
Systems and also the internet are growing daily and lots of new computers along with other products are using IP. The configuration of IP addresses ought to be simple. We are able to configure IP version 4 address either configured by hand or instantly while using DHCP. Nowadays days as just about all products are IP enabled we ought to have simpler way to configure favour these units configured instantly without majorly counting on some administration.
Internet routing table expansion
A routing table selects the very best path for delivering data. Due to the quantity of servers attached to the Internet increases, that also increase the amount of a route. These IP version 4 routes use memory and processor sources on the internet routers.
Insufficient finish-to-finish connectivity
Inside the IP version 4 network, NAT is usually used. NAT allows to provide a means for multiple devices to talk about just one public IP version 4 address. This really is hard for technologies that require finish-to-finish connectivity. Since the public IP version 4 address shared and also the IP version 4 addresses of the internal network host remain hidden.
Service quality (QoS)
IP version 4 addresses provide Service quality (QoS). It depends on the 8 bits TOS field and also the identification from the payload. IP version 4 Kind of Service (TOS) field has limited functionality and payload identification.
