Two computers with different network IDs can have the same host ID. However, the combination of the network ID and the host ID must be unique to all computers in communication with each other. Hosts depend on a second number called a subnet mask to help determine which portion of an IP address is the network ID and which portion is the host ID. The subnet mask defines where the network ID stops and the host ID starts. It is easier to see why this works if you step away from the decimal representation for a moment and look at the numbers in their binary format. Figure 13-1 depicts a single IP address shown in both decimal and binary format. A subnet mask is also shown in both formats. In binary format, a subnet mask always represents a string of unbroken ones followed by a string of unbroken zeroes. The position of the change from ones to zeroes indicates the division of network ID and host ID in an IP address.

If you expect that categories are already cached in the persistence context or the second-level cache, then you need only the identifier value (the key to the cache). This therefore reduces the amount of data fetched from the database. The following SQL is slightly more efficient:

135.109.15.42 255.255.0.0 135.109.0.0 0.0.15.42

Figure 13-1

You can use the iterate() method for this:

IP addresses are organized into classes that help define the size of the network being addressed, a system referred to as classful IP addressing. Five different classes of IP addresses define different-sized networks that are capable of holding varying numbers of hosts. Classful IP addressing is based on the structure of the IP address and provides a systematic way to differentiate network IDs from host IDs. As you learned earlier, there are four numerical segments of an IP address, ranging from 0 to 255. Here, those segments are represented as w.x.y.z. Based on the value of the first octet (w), IP addresses are categorized into the five address classes listed in Table 13-1.

Query categoryByName = session.createQuery("from Category c where c.name like :name"); categoryByName.setString("name", categoryNamePattern); Iterator categories = categoryByName.iterate();

Table 13-1

The initial query retrieves only Category primary key values. You then iterate through the result; Hibernate looks up each Category object in the current persistence context and, if enabled, in the second-level cache. If a cache miss occurs,

Range of First Octet 1 126 128 191 192 223 224 239 240 255 Number of Available Network Number of Segments Available Hosts 126 16,384 2,097,152 N/A N/A 16,777,214 65,534 254 N/A N/A

Classes A, B, and C are available for registration by public organizations. Actually, most of these addresses were snapped up long ago by major companies and Internet service providers (ISPs), so the actual assignment of an IP address to your organization will likely come from your chosen ISP. Classes D and E are reserved for special use. The address class determines the subnet mask used, and therefore determines the division between the network ID and the host ID. For class A, the network ID is the first octet in the IP address (for example, the 98 in the address 98.162.102.53 is the network ID). For class B, it is the first two octets; and for class C, it is the first three octets. The remaining octets not used by the network ID identify the host ID.

Hibernate executes an additional SELECT for each turn, retrieving the full Category object by its primary key from the database In most cases, this is a minor optimization It s usually much more important to minimize row reads than to minimize column reads Still, if your object has large string fields, this technique may be useful to minimize data packets on the network and therefore latency It should be clear that it s really effective only if the second-level cache region for the iterated entity is enabled Otherwise it produces n+1 selects! Hibernate keeps the iterator open until you finish iteration through all results or until the Session is closed You can also close it explicitly with orghibernateHibernateclose(iterator) Also note that Hibernate Criteria and Java Persistence, at the time of writing, don t support this optimization.

Remember the IP address ranges that fall into each class and the default subnet mask for each class. This information not only helps to determine how a classful IP addressing scheme will apply to a situation, but also how to customize a scheme using the classless method (discussed next).
