18、tifying a specific device on an IP network.Each Device has its own unique addressThe address tells the device and the network who can communicate on the networkHow is an IP address created?What makes up an IP address?Two PartsNetwork ID: which tells you want network the device belongs tooDevice ID:

19、which gives you a device specific identifierHavent I seen something like this before?192.168.100.10How is an IP address created?(555) 555-5555Area CodePhone NumberArea Code: identifies the city, area, network that the telephone belongsPhone Number: identifies the specific phone in that areaHow is an

20、 IP address created?(555) 555-5555192.168.100.10Network IdentifierDevice IDNetwork Identifier: like an area code all devices on that network have the same network identifierDevice ID: is unique number that is used to specifically identify a device on a network much like your phone has a unique phone

21、 number Subnet mask192.168.100.10Network IdentifierDevice IDThe subnet mask designates which “octets” are the network number and which is the Device number. In its basic form, which octets have a 255 denote which octets in the IP address are the network number.In the above, example the first three o

22、ctets have a 255 meaning that the first three octets are the network number. In this case, the network number is 192.168.100 and the device ID is 10So how do you know which is the network number and which is the device number? How is an IP address created?255.255.255.0192.168.100.10255.255.0.0192.16

25、s by accident where the subnet masks are different, but because the IP address has a match numbering “scheme” the two devices might be able to “talk”. Success is dependant on the devices and the systems connecting the two together. Some audio media servers are not tolerant of this type of configurat

27、assigned one by a device on the network (DHCP) and an address was not assigned manually by the installer, so the device assigns itself an address following a standardized numbering convention.StaticThe installer manually enters an IP address and subnet mask into the device. Upon bootup the device wi

28、ll us this address to communicate, even if a DHCP device is on the network.Advantages:You know what IP addresses your devices are usingDisadvantagesIts very easy to accidentally type in the address incorrectly or to use the same address twice.A lot of effort with very little paybackWhere do address

29、come from?Where do address come from?DHCP (Dynamic Host Configuration Protocol)A device on the network temporarily assigns an unused valid IP address to the computer. In home networks, the switch/gateway usually provides this service.The computers network card must be configured to look for a DHCP d

30、evice.AdvantagesMust common method of acquiring an IP addressWorks automaticallyAddress are unique and follow the same schemeDisadvantagesIf you need the address you have to look it upAddress could changeWhere do address come from?AutoIPUsed as a fallback method of assigning IP addresses in the even

31、t that a static address or a DHCP provided address are not present. These address normally start with 169.Sometime different companies will use their own variations of AUTOIP. This is seen in StreamNet products.AdvantagesFallback to ensure all devices have an IPAllows companies to use there own IP a

32、ddress scheme without requiring a DHCPDisadvantagesCan be confusing to installers in environments that support static and DHCPWhat happens when a computer boots up?First, The computer checks to see if there is a static IP addressIf there is an address then the computer uses that address.If there is

33、no static IP addressThen it looks for a DHCP device and asks for an IP addressIf it finds a DHCP device then the computer will use that address.If it cannot find a DHCP device then the computer willThis process does not happen on StreamNet devices.In the event, that no static IP address or DHCP is a

34、vailable then the computer will assign itself an IP address using a IP address scheme determined by the computer.The address usually starts with 169Sometimes take up to 2 minutes for the DHCP process to time out and AUTOIP to start.StreamNet uses a variation of AutoIP. As the installer you specify a

35、 range of IP addresses and a subnet mask. When the device boots up it selects an IP address in that range, verifies that it is not in use and then uses that address.You can also manually assign a static IP address to each individual device.Both AutoIP and static addresses are configured using DigiLi

36、nX System Setup software.IP Addresses and StreamNetBy default StreamNet devices use address from to 55 with a Class A subnet.How do I choose an IP address range for my StreamNet enable system and for the sites network?Typically, the site will already have selected a specific IP Address scheme (usual

37、ly something like through 54) You will want to also use this range, but it is best to break the range into parts that are reserved for the various systems. For example:Static devices : through 0StreamNet devices: 1 through 50Site network: 51 through 54Dividing the IP addresses this way ensures that

38、desperate systems do not conflict with each other.Larger commercial networks will use different IP address ranges, but the principal still applies. The sites IT staff can assist you in determining what range to use.IP Addresses and StreamNetTech TipVerify that you have selected the NIC in DigiLinX S
