TRANSCRIPT
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
