This slides covers basic introduction to IPv6 .

1. By Md. Khalid Saifullah Gazi

2.  IPv6 is Internet Protocol version 6
 128 bit address ; 2128 = 3.4X1028
Example:
FE38:DCE3:124C:C1A2:BA03:6735:EF1C:683D
Abbreviated form of address
FE80:0023:0000:0000:0000:036E:1250:2B00
→FE80:23:0:0:0:36E:1250:2B00
→FE80:23::36E:1250:2B00
Double colons (::) representation
– RFC5952 recommends that the rightmost set of :0: be
replaced
with :: for consistency
• 2001:db8:0:2f::5 rather than 2001:db8::2f:0:0:0:5
Practice : 2001:0db8:0000:0000:00a0:0000:0000:10bc

3. Ans
 2001:0db8:0000:0000:00a0:0000:0000:
10bc
 2001:db8:0:a0::10bc

4.  IPV4 address
running out
 Plenty of address
space (Mobile
Phones, Tablet
Computers, Car
Parts, etc. J )
 Solution of very
complex hierarchical
addressing

6.  20 =1;
 21 =2;
 22 = 4 ;
 23 = 8 ;
8 4 2 1
= 1 0 1 0
= 10 = A

7. 2001:0DB8:DEAD:BEEF:1AB6:503F:A804:71D9
0010 0000 0000 0001 0000 1101 1011 1000
1101 1110 1010 1101 1011 1110 1110 1111
0001 1010 1011 0110 1001 0000 0011 1111
1010 1000 0000 0100 0111 0001 1101 1001

9. Provider A has been allocated an IPv6
block
2001:DB8::/32
• Provider A will delegate /48 blocks to
its customers
• Find the blocks provided to the first 4
customers

11. 8 4 2 1

12. No checksum at the IP network layer
No hop-by-hop fragmentation

14.  RIPng
 Static
 EIGRP
 OSPFv3
 IS-IS
 BGP

15. Runs over a link, not a subnet
Multiple instances per link
Topology not IPv6 specific
1.Router ID
2. Link ID
Standard authentication mechanisms
Uses link local addresses
Generalized flooding scop
Two new LSA types
