Hello Brain,

Here is the entry

The SOA is
195.187.24.in-addr.arpa IN SOA  lab-a.lab.test.net. abuse.test.net. (
                                2006101700 ; serial
                                7200       ; refresh (2 hours)
                                600        ; retry (10 minutes)
                                604800     ; expire (1 week)
                                86400      ; minimum (1 day)
                                )

Here are some sample entries

1                       PTR     ool-18bbc301.static.goog.net.
10                      PTR     ool-18bbc30a.static.goog.net.
100                     PTR     ool-18bbc364.static.goog.net.
101                     PTR     ool-18bbc365.static.goog.net.
102                     PTR     ool-18bbc366.static.goog.net.

Could you please tell me what I should be doing wrong.

For me record is not getting created in the first place. It is returning 
null.

When I try to debug there is a exception like

wireparseexception below

Here is the data I am passing

[-61, -69, -61, 1]  in byte array.

public
Name(DNSInput in) throws WireParseException {
	int len, pos, currentpos;
	Name name2;
	boolean done = false;
	byte [] label = new byte[MAXLABEL + 1];
	boolean savedState = false;

	while (!done) {
		len = in.readU8();
		switch (len & LABEL_MASK) {
		case LABEL_NORMAL:
			if (getlabels() >= MAXLABELS)
				throw new WireParseException("too many labels");
			if (len == 0) {
				append(emptyLabel, 0, 1);
				done = true;
			} else {
				label[0] = (byte)len;
				in.readByteArray(label, 1, len);
				append(label, 0, 1);
			}
			break;
		case LABEL_COMPRESSION:
			pos = in.readU8();
			pos += ((len & ~LABEL_MASK) << 8);
			if (Options.check("verbosecompression"))
				System.err.println("currently " + in.current() +
						   ", pointer to " + pos);

			if (pos >= in.current())
				throw new WireParseException("bad compression");

When I do a nsupdate and works for these

1.195.187.24.in-addr.arpa 600 IN PTR www.junk.com.

Thanks in advance
