DHCPv6 Non-Configurable Registry Settings (Windows Embedded CE 6.0)
1/6/2010
The following values are created and used internally by DHCPv6. They should never be modified using the Registry Editor. They are listed here for reference only. These entries are located under the HKEY_LOCAL_MACHINE\Comm\<Adapter Name>\Parms\Tcpip subkey.
Note
The default registry values vary depending on which Catalog items you include in your OS design. For more information, see topic Default Registry Settings.
The following table shows the non-configurable values for the HKEY_LOCAL_MACHINE\Comm\<Adapter Name>\Parms\Tcpip subkey.
| 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 PrefixT1 time 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. |
