(Specify the fixed DNS server)
<count>
• Destination definition number
Specify the destination definition number with a decimal value from 0 to 49.
The specified value is sorted and renumbered forward when setting was completed.
If any destination definition with a same definition number exists, it will be inserted
before the existing one.
<address>/<mask>
Specify the IPv4 address for reverse lookup and the number of mask bits.
• IPv4 address for reverse lookup/number of mask bits (or mask value)
Specify a combination of the IPv4 address for reverse lookup and the number of mask
bits.
For the mask value, specify successive 1s following the most significant bit (MSB).
• any
Specify it when all addresses are subject to reverse lookup.
<ipaddress>
• DNS server IP address
Specify the IPv4 address of the DNS server that forwards a request.
The allowable range is as follows:
1.0.0.1 to 126.255.255.254
128.0.0.1 to 191.255.255.254
192.0.0.1 to 223.255.255.254
Configuration mode (admin class)
Set the reverse lookup conditions for proxy DNS.
The explanation for each command is as follows.
• Discard the requirement for forwarding
proxydns address <count> <address>/<mask> reject
Set the filter that disables forwarding the specified DNS request.
The host name to be specified in <qname> is available when limiting the access to the
specified host (group) even if it is registered in the DNS database. A host name that
has satisfied filtering conditions will be discarded.
• Specify static DNS server
proxydns address <count> <address>/<mask> static <ipaddress>
Specify the IP address to which the specified DNS request is to be forwarded.
The route leading to the destination is determined based on IP routing.
It is assumed that no reverse lookup conditions for proxy DNS are set.
