Layer 2 addresses are MAC addresses, which are hard coded in to networking devices, such as network cards. 'IP' addresses are classed as layer 3 addresses.

the 'layers' come from the OSI model

hope that helps :)

Netgear fs516 default ip address


switches do not normally have ip addresses as they are layer 2 network devices. They work on the MAC address of each network card attached to it to direct the network packets of data to the correct Network card.
Cisco Switches have an IP address but it is a virtual ip address used to remotely log into a Cisco Switch via IP but has nothing to do with the switching function however this is not a cisco switch.
Routers have IP addresses and use them to switch IP addressed packets to other Networks that have Routers connected to Switches.

Does a Ethernet Switch(Unmanaged) have a default IP address?


There is a user guide on the tp-link web site. It looks as if this is just a layer-2 switch (ethernet) and there is no user configuration to enter. The IP addresses would come from another device on your LAN. A router or a server that supports layer-3 (IP) would issue addresses by running a DHCP server process on it.

Port forwarding on Linksys SRW224G4P


Google took me straight to the manual. This is a Switch not a router so it operates in layer-2 (ethernet). Layer-2 ports are the interfaces on the back of the switch. You want a router that can do layer-3 TCP/IP port forwarding. Layer-3 ports are unsigned 16-bit integers associated with an IP address and a protocol.

Whats is the default ip address of this switch


Ethernet is layer-2 and deals in 48-bit ethernet addresses. IP addresses are assigned by routers (not switches) that operate on layer-3 protocols.

What are the static ip for leased lines


You have not provided enough information to answer this definatively. However, one possible answer exists, if this relates to leased lines from a service provider or telephone company. Leased lines involve a physical connection and a network layer logical connection. At the physical layer, there are no assigned IP addresses, just devices that transform analog to digital signals (and vice versa).. The installation person should have checked signal conductivity as part of the service. The next layer up (TCP/IP), has IP addresses, either given to you on some paperwork, or via dynamic IP Address assignment request. If the service promises a static IP address, then your paperwork (for example, setup instructions) contains any access authentication (required); a group of 4 or 6 numbers, separated by periods; and at least a 2nd set of 4/6 numbers designated as your default route IP. Otherwise, you may have to turn on DHCP and let your external router port retrieve your assigned (static) IP address from the network device at the other end of your network connection. The returned IP address is your assigned static IP address. Just make sure it is not 10.x.x.x, or 127.0.x.x, or 192.168.x.x. Those address ranges are not routable in the larger Internet space.

No network problems 3com phones can't get connected to dhcp


Assuming you are talking about remote phones, you need to program the NCP (call processor) IP into the phones manually or add option 187 to your DHCP scope. The phones are able to DHCP the just also need to know what the IP address of the phone system to connect to is. If the phones are on your local network then this is all unnecessary. They work at layer 2 locally and don't need to use an IP address or DHCP.

Hello wots an router somthing to do withs to internet and how do reinstall it


To understand what a router does, you need to know a little bit about how the Internet works. The Internet, the huge world-wide computer network that we surf the World Wide Web on, uses the TCP/IP networking protocol. Data sent over a TCP/IP network is broken down into chunks called "packets", and in order for these packets to get where they need to go on the Internet, something is needed to route them to their destinations (hence the name router). The many networks that make up the Internet are connected to each other by routers, and the routers determine what packets go where. Routers are level 3 devices on the OSI model, which means that they function at the network layer. The OSI model has 7 levels, and each one represents a function when it comes to data communication between two or more computers on a computer network. To understand what I'm talking about in the next paragraph, you need to know about the OSI model and what layer the router represents.

When the average computer user thinks of a router, they probably think of the kind that you can purchase at your local computer store, as opposed to the big ones that route packets on the Internet. That smaller kind of router allows you to share an Internet connection with multiple computers without having to use a computer that acts as a "gateway". If you have a computer network at home and the center of it is a hub or a switch, you need to use a computer that acts as a gateway ("host" computer), as hubs and switches cannot do what a router does (hubs and switches are two other devices that you can purchase at your local computer store to create a network between two or more computers). A router can "intelligently" route TCP/IP packets to IP addresses (unique identifiers on a TCP/IP network) at layer 3, while a hub is just a dumb layer 1 device that sends out packets to all of the computers attached to it, regardless of who sent them out and who they're intended for. A switch is a layer 2 device that routes Ethernet frames by MAC address; Ethernet is a networking standard that home networks are based on, a frame is the Ethernet equivalent of a TCP/IP packet (chunk of data), and a MAC address is a computer's unique identifier at layer 2 (datalink) on an Ethernet network. Although a switch is "smarter" than a hub, it still can't do what a router does. The functions that a router performs are necessary for communication between the computers on your network and computers on other networks on the Internet at the network layer (TCP/IP). Probably the most important thing that a router does is perform NAT, which stands for Network Address Translation. NAT is a technology that allows computers on a network behind an Internet connection to communicate with computers outside the network; to the rest of the Internet the network is a single IP address (the one your ISP gave you), and NAT allows for incoming and outgoing connections between the computers on the network who have their own "internal" IP addresses and the computers outside the network who see only the ISP-assigned IP address. A "gateway" computer using Internet connection sharing software like the kind that Windows comes with performs the same functions as a hardware router, but there are some disadvantages that come with using that setup, like how all of the computers on the network lose Internet access if the gateway computer is offline. If you want to share an Internet connection between two or more computers in your home, a hardware router is the best thing to get for it.

Layer3


Which model are you talking about ? I have included both


Here is the OSI model
Layer 1 = physical medium & signal on the wire (physical)
Layer 2 = MAC Address and SNAP (ATM) (data link)
Layer 3 = IP Addressing V4 V6 (network)
Layer 4 = TCP/UDP (RTP, RTSP) (transport)
Layer 5 = Duplexing Half or full (Session)
Layer 6 = HTTP, FTP, SNMP (presentation)
Layer 7 = Web browser, FTP Client, (application)

TCP Model:
Layer 1 = physical medium & signal on the wire (physical) (Hub and reapeter)

Layer 2 = MAC Address and SNAP (ATM) (data) (Switches and bridges)

Layer 3 = IP Addressing V4 V6,
Layer 4 = TCP/UDP (RTP, RTSP) (Internetwork) (Firewall, IPSEC) Routers

(This function is split between 4&5) Duplexing Half or full

Layer 5 = , HTTP, FTP, SNMP, Web browser, FTP Client, (application) (programs)


I hope this helps,

Thank you,

Layer3


http://en.wikipedia.org/wiki/OSI_model

Layer3 is the Network Layer of the OSI Model, IP operates at Network Layer, OSI Model comprises of 7 layers, Application, Presentation, Session, Transport, Network, Datalink, Physical layers.

It is a model to follow when you are building Operating systems, applications to be used on the internet or compatibility with others.

Hope this helps
