Ipv4 vs ipv6
Ipv4 numeric
192.168.0.1
Each 0-255 values
Total 4billions ip addresses
Problem: now morethan 4bn devices to allocate ip addresses
Ipv6: includes alphanumeric value.
Alphabet for double digit number, when converting into binary.
With ipv6 morethan deletion address enough to address the current demand.
Ipv6 Limitation:
#only ipv6 device to ipv6 works, no backward compatibility
Ipv4 to ipv6
ISP providers not upgraded to hardware to support ipv6
Founded in 1983 32 bit address 2^32 4.3bn address vs 128 bit address, 1994,
340 undecillion unique address space
340 times 10 to the 36th power, or 340 trillion trillion trillion possible IP addresses.
Ipv4 uses
Network address translation) devices which allows single NAT address can mask thousands of non-routable addresses, making end-to-end integrity achievable.
Ipv6 allows direct address because lot of availablity of ip addresses.
Ipv4,ipv6 Headers &header lengths 12, 8 , 20,40
Packet size 576 bytes, 1208 bytes.
DNA mapping through A records
AAAA Records.
Binary address seperated by ., Ipv6 :
ipv4 A-E address, 192,162,18.0.1
Ipv6 stores unlimited: 2001:0db8:0000:0000:0000:ff00:0042:7879
Ipv6 doesn’t support broadcast, but anycast
Protocol) to map to MAC address whereas IPv6 uses NDP (Neighbour Discovery Protocol) to map to MAC address.
majority of devices not compatible with IPv6, and the dual-stack technology ensures that legacy IPv4 devices will still work for the foreseeable future.
why ipv6 is better than ipv4
Security
Ipv4 not security in mind, ipv6 focused on security.
Efficiency: no checksum in router allows faster pocket processing.& Routing
Faster& simplified routing
Direct data flow: multicast allows bandwidth intensive pockets (multimedia)
Elimination of NAT
network address translation.
is ipv6 better than ipv4 for gaming
Withmukticast & elimination of NAT it’s good for gaming.
Ask your isp to provide ipv6
