Maximizing use of the product
Using the netvolante DNS service
(Continued from the previous page)
Host names assigned
by the netvolante DNS
service
When using the netvolante DNS service, you can
obtain a host name in the format of "(Your desired host
name).xxx.netvolante.jp", where "xxx" is an arbitrary
string automatically assigned by the netvolante DNS
6
server. This function is convenient because you do
not have to change settings each time the global
IP address is changed.
NOTE
• The netvolante DNS service can be set only for
terminal provider connection. It cannot be set for
network connection or LAN-to-LAN connection. Even
for terminal CATV provider connection, it cannot be
set if the IP address is fixed on the WAN side.
• Only a single host address can be obtained for a unit
of the product.
• Note that your desired host name is not always
available.
• Lookup of the obtained host address is possible, but
reverse lookup is not possible.
• The netvolante DNS service uses a Yamaha original
protocol, and the obtained host address cannot be
registered with external dynamic DNS servers.
• The netvolante DNS service can be used only in an
environment where a global IP address is assigned
by a provider. Note that the following IP addresses
are not global IP addresses:
- 10.0.0.0 - 10.255.255.255
- 172.16.0.0 - 172.31.255.255
- 192.168.0.0 - 192.168.255.255
• Depending on the provider you are currently using,
the registered/updated host name settings may
not be reflected on the netvolante DNS service
immediately.
