Device Overview
During the practical parts of the course you work with an emulated network environment. All in all you'll work with a over a dozen of different hosts. On this page you can find an overview of hosts, their MAC addresses (introduced in Part 1 of the course) and IP addresses (introduced in Part 2 of the course).
You can use this page as simple lookup table if you need to e.g. find out which IP/MAC address belongs to which host or vice versa.
General Network Information
In general we use the IPv4 and IPv6 documentation prefixes for our purpose. They are not routable over the Internet, but for the course we assume they are.
Find the an overview over the most relevant prefixes used below.
|
IP Range |
Description and use in course |
|
2001:db8::/32 |
IPv6 Documentation prefix, used as prefix for most IPv6 addresses we use in the course that are assumed to be publicly routable. |
|
fe80::/64 |
IPv6 link local prefix, each host automatically generates a link local address for each interface with this prefix. |
|
192.0.2.0/24 , 198.51.100.0/24, 203.0.113.0/24 |
IPv4 Documentation prefix (RFC 5737).Used similar to the IPv6 documentation prefix when we need IPv4. |
|
10.0.0.0/8, 192.168.0.0/16, 172.16.0.0/12 |
IPv4 private address ranges. Not routable over the Internet. Used when we need IPv4 addresses that we assume to be not routable over the Internet. |
Simple Hosts
Simple hosts are all devices with only one network interface (eth0) connecting them to another host or router.
You can find an overview about all hosts in our different setups here, roughly ordered by the order of the course parts they appear in:
|
Hostname |
MAC address |
global IP address |

Routers
Routers are all devices with more than one network interface (eth0), routing and forwarding traffic between other connected routers or hosts. As routers have multiple network interfaces, the according interfaces eth0-eth4 are also given below:
|
Hostname |
MAC address |
global IP address |
|
router1 |
eth0: 02:00:00:00:00:f1 eth1: 02:00:00:00:00:f2 eth2: 02:00:00:00:00:f3 eth3: 02:00:00:00:00:fa |
eth0: 2001:db8:bee:11::1 eth1: 2001:db8:bee:22::1 eth2: 2001:db8:bee:c1::fe eth3: 2001:db8:bee:c2::fe |
|

Subnets
All the subnets used in our setups can be found below. Note that for direct connections between routers we use /127 subnets, as specified in RFC 6164. Subnets that only occur in one part of the course are marked accordingly:
