Network services

The LAA provide basic network services to the DUT on the private ethernet port only.

DHCP

The LAA will answer to dhcp requests with always the same IPv4 configuration:

Multiple MAC

The dhcp server will revoke all the dhcp leases every time the private ethernet connection goes down.

This allows for the DUT to change MAC address from one boot to another while still being assigned the same IPv4.

The dhcp server also advertises the LAA (198.18.0.1) as ntp, dns and next server (pxe boot).

The LAA provides a DNS server on the private ethernet port at 198.18.0.1.

The DNS server uses the locally provided DNS server on the public ethernet port and fallbacks to:

cloudflare: 1.1.1.1, 1.0.0.1, 2606:4700:4700::1111 and 2606:4700:4700::1001
google: 8.8.8.8, 8.8.4.4,2001:4860:4860::8888 and 2001:4860:4860::8844

The LAA provides an NTP server on the private ethernet port at 198.18.0.1.

The LAA uses 0.openembedded.pool.ntp.org as the reference pool.
