HP 4800G Series Configuration Manual page 286

The domain name and DNS server address on subnets 10.1.1.0/25 and 10.1.1.128/25 are the
same. Therefore, the domain name suffix and DNS server address can be configured only for
subnet 10.1.1.0/24. Subnet 10.1.1.128/25 can inherit the configuration of subnet 10.1.1.0/24.
In this example, the number of requesting clients connected to VLAN-interface 1 should be less than
122, and that of clients connected to VLAN-interface 2 less than 124.
