 Benefits of IPv6
 Running out of address space
 Possible IP address exhaustion before 2011
 Increase from 2^32 to 2^128 addresses
 192.168.0.1 (decimal) vs
fe80:f2f0:9e9a:b10c:a908:2000:dc6a:1028 (hex)
 Static Header vs. Dynamic header
 IPv6 is flexible

IPv6
 Benefits of IPv6
 Network and routing simplification
 No need for subnets, NAT, DHCP
 Routing more efficient
Security
 Provided Security
 Built in IPsec
 Other security can be added with dynamic header
 Potential Security Issues
 Transition Mechanisms Exploited
 Holes in secure systems
 Hard to detect intrusion
 New technology provides different/new possible
exploits
 Problems facing IPv6
 Compatibility
 IPv6 is not compatible with IPv4
 Software and hardware have to be upgraded
 Implementation
 Will have to coexist with IPv4 for a long time
 Dual backbone routers, IPv6 over IPv4 tunnels,
protocol translation mechanism
 Performance
 Mixed IPv4 and IPv6 increases complexity
 Header increased from 20 to 40 bytes
 Flow based rather than packet based
 Conclusion
 IPv6 is needed and will be implemented
over time
 Mixed IPv4 and IPv6 networks will make
things more complex
 IPv6 will not achieve full potential until it is
fully implemented
Lab Procedure




Remove the IPv4 IP addresses
Install the IPv6 module on Redhat 8.0 and 7.2
Install the IPv6 protocol on Windows XP
Use ethereal to sniff and IPv6 ping and ssh 6
session
 Upgrade Red Hat 8.0 ftp server vsftpd and edit
conf file to make it IPv6 compatible
 Sniff IPv6 ftp session
