4. The 64 bit WEP data encryption method allows for a five character 40 bit input Additionally 24 factory set bits are added to the forty bit input to generate a 64 bit encryption key The 24 factory set bits are not user configurable This encryption key will be used to encrypt decrypt all data transmitted via the wireless interface Some vendors refer to the 64 bit WEP data encryption as 40 bit WEP data encryption since the user configurable portion of the encryption key is 40 bits wide The 128 bit WEP data encryption method consists of 104 user configurable bits Similar to the forty bit WEP data encryption method the remaining 24 bits are factory set and not user configurable Some vendors allow passphrases to be entered instead of the cryptic hexadecimal characters to ease encryption key entry 128 bit encryption is stronger than 40 bit encryption but 128 bit encryption may not be available outside of the United States due to U S export regulations When configured for 40 bit encryption 802 11 products typically support up to four WEP Keys Each 40 bit WEP Key is expressed as 5 sets of two hexadecimal digits 0 9 and A F For example 12 34 56 78 90 is a 40 bit WEP Key When configured for 128 bit encryption wireless products typically support four WEP Keys but some manufacturers support only one 128 bit key The 128 bit WEP Key is expressed as 13 sets of two hexadecimal digits 0 9 and A F For example 12 34 56 78 90 AB

IANA at www iana org The Internet Protocol IP uses a 32 bit address structure The address is usually written in dot notation also called dotted decimal notation in which each group of eight bits is written in decimal form separated by decimal points For example the following binary address LLOOOOLL OO0LOO0L0 OO 001 00 O00 001 dL is normally written as URS ko ree stare ie ae B 2 Network Routing Firewall and Basics Reference Manual for Cable DSL Wireless Router WGR614 The latter version is easier to remember and easier to enter into your computer In addition the 32 bits of the address are subdivided into two parts The first part of the address identifies the network and the second part identifies the host node or station on the network The dividing point may vary depending on the address range and the application There are five standard classes of IP addresses These address classes have different ways of determining the network and host sections of the address allowing for different numbers of hosts on a network Each address type begins with a unique bit pattern which is used by the TCP IP software to identify the address class After the address class has been determined the software can correctly identify the host section of the address The follow figure shows the three main address classes including network and host sections of the address for each address type Class A E S l Network Node Class
