GROUP INFORMATION ================= The table below lists DNS domain name, internal network prefix and address of router's external interface (on 130.236.189.0/27 or 130.236.178.0/27) for each group. Note that you need to calculate the netmask and broadcast address for each network yourself. Avoid using the lowest address of the internal network for anything. -------------------------------------------------------------------- Group DNS domain name Internal network Router's ext if
