"IRULE" using IP and FQDN

Just to clarify, here is the irule that we're using based on IP. How this can be modified to include FQDN or domain as destination.

when RULE_INIT {

 Debug logging level (0 = logging disabled, 1 = logging enabled)
set static::_proxy_bypass_debug 0


 Proxy Bypass Source IP datagroup name (as configured under Local Traffic > iRules > Data Group List)
set static::source_ip_proxy_bypass_RD1_dg "/Common/source_ip_proxy_bypass_RD1_dg"

 Proxy Bypass Destination IP datagroup name (as configured under Local Traffic > iRules > Data Group List)
set static::destination_ip_proxy_bypass_RD1_dg "/Common/destination_ip_proxy_bypass_RD1_dg"

}

when CLIENT_ACCEPTED {

 If client IP is in bypass list then don't load balance client to ironports, otherwise load balance to default pool.
if { not (([class match [IP::client_addr] equals $static::source_ip_proxy_bypass_RD1_dg]) || ([class match [IP::local_addr] equals $static::destination_ip_proxy_bypass_RD1_dg])) } {
    if { $static::_proxy_bypass_debug } { log local0. "Client connection proxied to ironports. Client Source IP [IP::client_addr] or Client Destination IP [IP::local_addr] is not in Datagroups. Server selected is  [LB::server]" }
    return
} else {
    if { $static::_proxy_bypass_debug } { log local0. "Client connection not proxied to ironports. Client IP [IP::client_addr] or Client Destination [IP::local_addr] is in Datagroups." }
    forward

} }
