Lab addressing - the issues

● Brief overview of current IPV4● Suggested IPV4 structure● IPV6 overview● Port forwarding and IPV6● Possible IPV6 structure

Lab addressing - current state

● 10.x.x.x/8 address range● Various ranges for device classes

○ 10.0.x.x - Lab infrastructure■ 10.0.0.x - Servers■ 10.0.1.x - PDUs■ …

○ 10.2.x.x Production dispatchers○ 10.3.x.x Staging dispatchers○ 10.254.x.x DHCP served to DUTs

Lab addressing - restructure

● Keep 10.x.x.x● Subnet in groups● Higher security

○ ACLs○ Variable DHCP lease times

IPV6 addressing - Overview

● 128-bit address: Colon separated 2 byte hextets● Site Prefix or Global Routing Prefix

○ Assigned by ISP● Subnet within LAN● Local Interface ID● Double colons can be used to indicate a run of zeros

Example: 2001:0DB8:0001:5270:0127:00AB:CAFE:0E1F/64

IPV6 and Port Forwarding

● Possible to be directly addressed

Suggested IPV6 structure
