    ZyAIR G-405 User’s Guide Appendix B IP Subnetting IP Addressing Routers “route” based on the network number. The router that delivers the data packet to the correct destination host uses the host ID. IP Classes An IP address is made up of four octets (eight bits), written in dotted decimal notation, for example, 192.168.1.1.
  • Page 86 ZyAIR G-405 User’s Guide Similarly the first octet of a class “B” must begin with “10”, therefore the first octet of a class “B” address has a valid range of 128 to 191. The first octet of a class “C” address begins with “110”, and therefore has a range of 192 to 223.
  • Page 87 ZyAIR G-405 User’s Guide writing the value of each octet. This is usually specified by writing a “/” followed by the number of bits in the mask after the address. For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with mask 255.255.255.128.
  • Page 88 ZyAIR G-405 User’s Guide In the following charts, shaded/bolded last octet bit values indicate host ID bits “borrowed” to form network ID bits.

Each subnet contains 6 host ID bits, giving -2 or 62 hosts for each subnet (all 0’s is the subnet itself, all 1’s is the broadcast address on the subnet).

    ZyAIR G-405 User’s Guide Appendix C Types of EAP Authentication This appendix discusses the five popular EAP authentication types: EAP-MD5, EAP-TLS, EAP-TTLS, PEAP and LEAP. The type of authentication you use depends on the RADIUS server. Consult your network administrator for more information.
  • Page 94 ZyAIR G-405 User’s Guide For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption. They are often deployed in corporate environments, but for public deployment, a simple user name and password pair is more practical. The following table is a comparison of the features of five authentication types.
