Bring the Tide Pool Online

Statically assign a global IPv6 address to an exhibit server, then verify it from the command line.

N10-009 · 1.4 APNET · 2.2.B APNET · 2.3.C

Scenario

You volunteer as the network admin for the Saltmarsh Tide Pool Aquarium, a small coastal science center. Your regional registry just allocated the aquarium a globally routable IPv6 /48 block, and you want to start testing IPv6 on the exhibit network. The upstream router is not yet sending Router Advertisements, so Stateless Address Autoconfiguration won't help — you'll configure the server's address by hand.

Carve your first internal subnet out of the /48 by setting the subnet field to 0010, giving a /64. Configure the address on the server's LAN‑Exhibit adapter, set the gateway to the router's link‑local address, then confirm with ipconfig.

Saltmarsh OS [Version 11.0.260] Type a command, then press Enter. Try: ipconfig (also: help, clear)

Tasks

  • Open IPv6 properties for LAN‑ExhibitSelect the wired exhibit adapter.
  • Switch to manual assignment"Use the following IPv6 address."
  • Enter the address 2001:db8:7a3c:10::a17:5eShorthand with :: is fine.
  • Set prefix length to 64Standard IPv6 LAN subnet size.
  • Set gateway to fe80::1The router's link-local address.
  • Apply the settingsCommit the configuration.
  • Run ipconfig and see the addressVerification step.

Check your understanding

1. How many bits long is the interface ID in a standard IPv6 unicast subnet like this one?
2. In 2001:db8:7a3c:10::a17:5e, which portion is the subnet (network) prefix?
3. Even with no manual config and no router, the OS still self-assigns one IPv6 address for on-link traffic. Which kind?
4. The adapter's MAC is 02:1a:2b:3c:4d:5e. Using EUI-64 (insert ff:fe in the middle, flip the 7th bit), what interface ID results?
