DNScache IP < 255

Is 172.376.22.* a router IP and why is the IP < 255?

DNSCACHE:
172.376.22.*=255.255.255.255
127.0.0.1=127.0.0.1
192.168.0.8=HB4444B5
192.168.0.5=O4444O
85.179.*.*=hb4444b5

  • Hi marevent,

    Here are some DNS Cache IP details from our ScreenOS Cookbook that might be helpful.

    dnscache handles localhost internally, giving it an A record of 127.0.0.1.
    dnscache handles 1.0.0.127.in-addr.arpa internally, giving it a PTR record of localhost.

    For the inbound traffic, you configure MIPs. In this recipe, assume that one MIP is in the same network with the interface’s IP address and one is not. If the MIP should be in a different network than the IP address on that interface, the interface must be in the Untrust zone, unless you use ScreenOS 6.l or later.
    set interface "ethernet0/1" mip 1.1.1.100 host 192.168.2.100 netmask 255.255.255.255 vr "trust-vr"
