This error indicates that the DNS name you are trying to resolve does not exist.

Things to try:

• Check that the hostname portion of the URL you are using is correct.

• Check that iPXE is using the correct DNS server. You can view the DNS server used by iPXE using the command show dns:

    iPXE> show dns
    net0.dhcp/dns:ipv4 = 10.0.0.6

• Check that your DNS server is prepared to handle recursive queries.

• Check that your DNS server is responding via UDP. iPXE will not retry via TCP if a response is too big.
