Bug? IPAddress.Parse("A1") not throwing FormatException

[John S.]

x86 .NET CF v 2.0.7045.0 (SP2?)
Windows CE 4.2 & 5.0

IPAddress.Parse("A1") returns 0.0.0.101 instead of throwing a
FormatException.

This breaks Dns.GetHostEntry & even Dns.GetHostByName (deprecated, but
must run the same codepath) if the host name is an A followed by
numbers.

Am I missing something?

Apparently this is an issue with WSAStringToAddress that is fixed in
CE 6.0.
