Format

Each line in the splitdns.config file uses one of the following formats:

dest_domain=dest_domain | dest_host | url_regex named=dns_ server

def_domain=def_domain search_list=search_list

The following table describes each field.

Field	Allowed Value
dest_domain	A valid domain name. This specifies that the DNS server selection be based on the destination domain. You can prefix the domain with an exclamation mark (!) to indicate the NOT logical operator.
dest_host	A valid hostname. This specifies that the DNS server selection be based on the destination host. You can prefix the host with an exclamation mark (!) to indicate the NOT logical operator.
url_regex	A valid URL regular expression. This specifies that the DNS server selection be based on a regular expression. See Specifying URL regular expressions (url_regex) for information about using regular expressions.
dns_server	This is a required directive. It identifies the DNS server for Content Gateway to use with the destination specifier. You can specify a port using a colon (:). If you do not specify a port, 53 is used. You can specify multiple DNS servers separated by spaces or by semicolons (;). You must specify the domains using IP addresses in dot notation.
def_domain	A valid domain name. This optional directive specifies the default domain name to use for resolving hosts. Only one entry is allowed. If you do not provide the default domain, the system determines its value from /etc/resolv.conf.
search_list	A list of domains separated by spaces or semicolons (;). This specifies the domain search order. If you do not provide the search list, the system determines the value from /etc/resolv.conf.
