is ipv6 faster than ipv4?
609523
Without NAT, IPv6 is faster than IPv4 That's in part because of the proliferation of network-address translation (NAT) by service providers for IPv4 Internet connectivity. ... By contrast, most mobile and broadband subscribers now have native IPv6 on their devices.

IP addresses are made up of binary values and drive the routing of all data over the Internet. IPv4 addresses are 32 bits long, and IPv6 addresses 128 bits long. IPv4 and IPv6 will be used for the foreseeable future; however there will be a transition from IPv4 to IPv6.

Adoption of IPv6 has been delayed in part due to network address translation (NAT), which takes private IP addresses and turns them into public IP addresses. ... But those IPv4 addresses are limited and nearing exhaustion to the point of having to be rationed. NAT helps alleviate the problem.

IPv6 applications that run on a dual-stack can also use the IPv4 protocol. IPv6 applications use an IPv4-mapped IPv6 address. ... The client can communicate with IPv4–only servers. The client can also communicate with IPv6 servers that run on either a dual host or an IPv6–only host.

IPv6 addresses An Ipv6 address uses 128 bits as opposed to 32 bits in IPv4. Because an hexadecimal number uses 4 bits this means that an IPv6 address consists of 32 hexadecimal numbers. These numbers are grouped in 4's giving 8 groups or blocks. The groups are written with a : (colon) as a separator.

Both IPv4 and IPv6 addresses come from finite pools of numbers. For IPv4, this pool is 32-bits (232) in size and contains 4,294,967,296 IPv4 addresses.

The simplest difference between Fast Ethernet vs Gigabit Ethernet is their speed. Fast Ethernet runs at the maximum speed of 100 Mbps and Gigabit Ethernet offers up to 1 Gbps speed which is 10 times faster than Fast Ethernet.

There are less than 4.2 billion available IPv4 IP addresses. In other words, there are more connected devices on the planet than there are unique, public IP addresses for them.

Why it matters: Routers have all sorts of speeds listed on their packaging — from 8Mbps (megabits per second) to 1900Mbps. In theory, the higher the number, the faster your internet speed — but don't get too caught up here. When comparing routers, you'll likely see labels touting AC1200, AC1750, AC 3200, and so on.

So in theory wired is faster. However, these speeds are only on your local network. Most high-speed internet connections range from 1Mbps to 25 Mbps. Even on faster internet connections you're only approaching 1/2 of the full throughput of your wireless system.

On the surface, it might seem that the IPv6 address format has a higher complexity and could clog things up from a routing perspective, but the subgroups of IPv6 actually enable faster delivery. IPv6 generates a 128-bit address, while IPv4 creates 32-bit addresses, so there will be room to grow with the new system.

No. An IP address is an integer. For IPv4, this is defined as the set of non negative integers which can be represented using 32 bits. For IPv6, the set is that of non negative integers which can be represented using 128 bits.

IPv6 uses 128-bit (2128) addresses, allowing 3.4 x 1038 unique IP addresses. ... IPv6 is written in hexadecimal notation, separated into 8 groups of 16 bits by the colons, thus (8 x 16 = 128) bits in total.

More Efficient Routing – IPv6 reduces the size of routing tables and makes routing more efficient and hierarchical. In IPv6 networks, fragmentation is handled by the source device, rather than a router, using a protocol for discovery of the path's maximum transmission unit.

The Internet Protocol version 4 (IPv4) is a protocol for use on packet-switched Link Layer networks (e.g. Ethernet). ... The Internet Protocol version 6 (IPv6) is more advanced and has better features compared to IPv4. It has the capability to provide an infinite number of addresses.

The IPv6 address space is 128-bits (2128) in size, containing 340,282,366,920,938,463,463,374,607,431,768,211,456 IPv6 addresses.
