Dns Servers - Cradlepoint CBA850 User Manual

User Manual / CBA850
a Netmask of 255.255.255.0 defines a network with 256
available IP addresses from 192.168.0.0 to 192.168.0.255.
Gateway or IPv6 Gateway: Specifies the next hop to be taken
if this route is used. A gateway of 0.0.0.0 implies there is no
next hop, and the IP address matched is directly connected to
the router on the interface specified: LAN or WAN.
Device: Select the network interface from the dropdown
menu (e.g. ethernet-wan). You can use this instead of defining
the IP address, especially in cases when the IP address is
changing.
Metric: Set the numerical priority of the route. Lower
numbers have higher priority.
Allow Network Access: (Default: Deselected.) Some static
routes will need an IP Filter Rule via the Firewall to allow
packets through the route without being blocked. Selecting
this option automatically creates this IP Filter Rule. If the IP/
Network Address falls outside the LAN IP range, you probably need to select this option.
Distribute: Allow this static route to be distributed via a routing protocol (BGP, OSPF, RIP, RIPng).

DNS SERVERS

DNS, or Domain Name System, is a naming system that translates between domain names (www.cradlepoint.
com, for example) and Internet IP addresses (206.207.82.197). A DNS server acts as an Internet phone book,
translating between names that make sense to people and the more complex numerical identifiers. The DNS
page for the device has these distinct functions:
• DNS Settings: By default your router is set to automatically acquire DNS servers through your Internet
provider (Automatic). DNS Settings allows you to specify DNS servers of your choosing instead (Static).
• Split DNS: Enable or disable the redirecting of specified domains to alternate DNS servers.
• Dynamic DNS Configuration: Allows you to host a server (Web, FTP, etc.) using a domain name that you
have purchased (www.example.com) with your dynamically assigned IP address.
• Known Hosts Configuration: Allows you to map a name (printer,
scanner, laptop, etc.) to an IP address of a device on the network.
DNS Settings
You have the option to choose specific DNS servers for your network
instead of using the DNS servers assigned by your Internet provider.
The default DNS servers are usually adequate. You may want to assign
DNS servers if the default DNS servers are performing poorly, if you
want WiFi clients to access DNS servers that you use for customized
addressing, or if you have a local DNS server on your network.
Mode: Automatic or Static (default: Automatic). Switching to "Static"
enables you to set specific DNS servers in the Primary DNS and Secondary DNS fields.
Primary DNS and Secondary DNS: If you choose to specify your DNS servers, then enter the IP addresses of the
servers you want as your primary and secondary DNS servers in these fields. The DNS server settings will be
