that is larger than the maximum, the EMG2926-Q10A will divide it into smaller
fragments.

requests that the EMG2926-Q10A sends to a DHCP server when getting a WAN IP
address.

if your ISP dynamically assigns DNS server information (as
well as the EMG2926-Q10A's WAN IP address). The field to the right displays the (read-
only) DNS server IP address that the ISP assigns.
Select

server's IP address in the field to the right.

IPv6 Tunneling
Use IPv6 tunneling when the local network uses IPv6 and the ISP has an IPv4 network. When the EMG2926-
Q10A has an IPv4 WAN address and you set
IPv4/IPv6
mode to
IPv4 Only
, you can enable IPv6 tunneling
to encapsulate IPv6 packets in IPv4 packets to cross the ISP’s IPv4 network.
