Table 72-15: DNS Parameters
The table defines the internal DNS table for resolving host names into IP
addresses.
The format of the ini file table parameter is:
[Dns2Ip]
FORMAT Dns2Ip_Index = Dns2Ip_DomainName,
Dns2Ip_FirstIpAddress, Dns2Ip_SecondIpAddress,
Dns2Ip_ThirdIpAddress;
[\Dns2Ip]
For example:
Dns2Ip 0 = DnsName, 1.1.1.1, 2.2.2.2, 3.3.3.3, ;
For more information, see 'Configuring the Internal DNS Table' on page

The table defines the internal SRV table for resolving host names into
DNS A-Records. Three different A-Records can be assigned to a host
name. Each A-Record contains the host name, priority, weight, and port.
The format of the ini file table parameter is:
[SRV2IP]
FORMAT SRV2IP_Index = SRV2IP_InternalDomain,
SRV2IP_TransportType, SRV2IP_Dns1, SRV2IP_Priority1,
SRV2IP_Weight1, SRV2IP_Port1, SRV2IP_Dns2, SRV2IP_Priority2,
SRV2IP_Weight2, SRV2IP_Port2, SRV2IP_Dns3, SRV2IP_Priority3,
SRV2IP_Weight3, SRV2IP_Port3;
[\SRV2IP]
For example:
SRV2IP 0 =
SrvDomain,0,Dnsname1,1,1,500,Dnsname2,2,2,501,$$,0,0,0;
