The following table shows the non-configurable values for the HKEY_LOCAL_MACHINE\Comm\<Adapter Name>\Parms\Tcpipsubkey.

Value : type Description

DhcpV6DNS: REG_MULTI_SZ

This value stores the IPv6 address of the DNS name server.

DhcpV6DomainList: REG_MULTI_SZ

This value contains the adapter-specific DNS domain name that is configured by the DHCP Server.

PrefixAddress: REG_MULTI_SZ

This value specifies the DHCPv6 configured prefix. This value can be any valid prefix. Its length is specified in PrefixLength.

PrefixLeaseObtainedHigh: REG_DWORD

This value is used by DHCPv6 client service to store the time (high) at which the lease on the IPv6 address for this adapter was obtained. The valid range for this value is 1–0xFFFFFFFF (hexadecimal).

PrefixLeaseObtainedLow: REG_DWORD

This value is used by DHCPv6 client service to store the time (low) at which the lease on the IPv6 address for this adapter was obtained. The valid range for this value is 1–0xFFFFFFFF (hexadecimal).

PrefixLength: REG_DWORD

This value is the length of the prefix, in bits.

PrefixPreferredLifetime: REG_DWORD

This value is the preferred lifetime of the DHCPv6 obtained prefix. This value is based on the number of seconds since the lease was obtained.

PrefixT1: REG_DWORD

This value is used by DHCP client service to store the time at which the service will first try to renew the lease on the IPv6 prefix for the adapter by contacting the server that granted the lease. The PrefixT1time is based on the number of seconds since the lease was obtained.

PrefixT2 :REG_DWORD

This value is used by DHCPv6 client service to store the time at which the service will try to rebind the lease on the IPv6 prefix for the adapter. The PrefixT2 time is based on the number of seconds since the lease was obtained.

PrefixValidLifetime: REG_DWORD

This value is the valid lifetime of the DHCPv6 obtained prefix. The PrefixValidLifetime is based on the number of seconds since the lease was obtained. The prefix is no longer valid after this time.
