IPv6 Exercices

Q1. How many hosts are described with the following prefixes?- 100- 48

Q2. Calculate the range of IPv6 addresses for:- 2001:4b58:27::/48 - 10.10.10.10/16

You may try to solve the task again with some help from http://www.tdoi.org

IPv4T1. Set the following aliases to your ethernet adapter

- Left group: 10.0.0.x/26- Right group: 192.168.0.y/27

T2. Try to ping your neighbors, for ex. “ping 10.0.0.5”.You will not be able to ping the IPs of the neighbor group.

T3. Set the following aliases to your ethernet adapter- Right group: 10.0.0.x/26- Left group: 192.168.0.y/27

T4. Try to ping your neighbors, for ex. See T2.You are able to ping the IPs of the neighbor group.

Attention: x and y must be unique in this class

IPv6T1. Set an IPv6 address to your ethernet adapter. Use 125 for prefix.

T2. Trace the route to www.6diss.org via both IPv6 and IPv4Use the following machine: student:Sofia011@hp.uni-plovdiv.bg

Hands on

T1. Find out for the both TCP and UDP protocols the following:- listen ports on your local PC- established TCP connections on your local PC

T2. Same as T1 but for student:Sofia011@hp.uni-plovdiv.bg

T3. Figure out the local opened TCP port (on your machine) due to the ssh session hp.uni-plovdiv.bg (from T2).

You may need some help:For T1: Use Windows Command Prompt and the command netstatFor T2: PuTTY may be useful for this task
