IPExt类怎么解析开始ip

[ginigal]

for (start = start * 9 + 262144; start < max_comp_len; start += 9) {
tmpInt = int2long(indexBuffer.getInt(start));
if (tmpInt >= ip2long_value) {
index_offset = bytesToLong(b, indexBuffer.get(start + 6), indexBuffer.get(start + 5), indexBuffer.get(start + 4));
index_length = ((0xFF & indexBuffer.get(start + 7)) << 8) + (0xFF & indexBuffer.get(start + 8));
break;
}
}

这段代码tmpInt 解析出来在是终止ip，请问起始ip要怎么解析
