2005-04-26  Michael Koch  <konqueror@gmx.de>

	* java/net/InetAddress.java: Made all hexadecimal numbers lowercase.
	Fixed typos in javadocs.
	(isSiteLocalAddress): Fixed handling of byte values.
	(isMCLinkLocal): Likewise.
	* java/net/Inet4Address.java
	(isMulticastAddress): Call super method.
	(isLoopbackAddress): Likewise.
	(isAnyLocalAddress): Likewise.
	(isLinkLocalAddress): Likewise.
	(isSiteLocalAddress): Likewise.
	(isMCGlobal): Likewise.
	(isMCNodeLocal): Likewise.
	(isMCLinkLocal): Likewise.
	(isMCSiteLocal): Likewise.
	(isMCOrgLocal): Likewise.
	(getHostAddress): Likewise.
