Specifying Hosts
B.1
Introduction
You can specify a host or group of hosts in F-Secure Anti-Virus for
Internet Gateways with a domain, subnet, IP address or hostname.
B.2
Domain
A domain is a partially qualified DNS domain name, preceded by a period.
It represents a list of hosts which logically belong to the same DNS
domain or zone. In other words, all hostname suffixes end in Domain.
Examples:
.example.com
.intra.example.com
To distinguish domains from hostnames, domains should be written with a
leading period.
B.3
Subnet
A subnet is a partially qualified Internet address in numeric (dotted quad)
form, optionally followed by a slash and the netmask, which is specified
as the number of significant bits in the subnet. It is used to represent a
subnet of hosts which can be reached over a common network interface.
If the explicit net mask is missing, omitted trailing digits specify the mask.
In this case, the netmask can only be multiples of 8 bits wide.
Domain name comparisons are case insensitive, and Domains are
assumed to be anchored in the root of the DNS tree. Therefore, domains
“.Example.com” and ”.example.com.” (note the trailing period) are
considered to be equal. Since a domain comparison does not involve a
DNS lookup, it is much more efficient than a subnet comparison.
