source

(a

member

of

a

source

address

list)

for

a

known

hosted

domain

(a

member
of
a

domain

list).
The
DNS

rule

specifies

which

response

(answer)

is

given

to

the

requesting

user’s

local

DNS

host
(D-proxy)
and

how

that

answer

is

chosen.

One

of

a

variety

of

balance

methods

is

used

to

determine

the
best
response

to

the

request,

based

on

the

status

and

load

of

the

GSS

host

devices.
