DNS Server Configuration
A DNS server is a server that contains a database of hostnames and their associated public IP addresses.
This server is used to resolve hostnames to a unique public IP address when requested.
When a user enters a URL e.g. www.netcommwireless.com into their browser, your router is contacting the DNS server and
requesting the webserver IP address.
Hostname URLs are easier for humans to understand and remember than IP address numbers. A host’s IP addresses can
change from time to time hence a DNS server is required to locate and translate a hostname.
DNS Servers can be used to block unwanted content, such as explicit material. By using a filtered DNS server, the hostname
of these materials will not be resolved, allowing parental control to accessible content.
Parental Control DNS are available as a free service or customizable paid service. For example: OpenDNS FamilyShield,
Norton ConnectSafe, Yandex.DNS, Comodo Secured, etc.
