I'm a bit confused, plus was wondering provided someone can fix self straight. Under a Native Area Network (LAN), whats is the communication record for the info packets under i.e. ethernet CAT5 cable that see to can the common routine. Will it TCP/IP? Although if the internet isn't utilized (no modem but just router) is it static TCP/IP? Configure Internet Protocol Version 4 (IPv4) Localize Area Network (LAN) Connections set one RV132W or RV134W VPN Router

Thank you in advance!

Usually, up with UDP real ICMP whichever can probably the most common, though loads other reporting exits and are used too.

Several protocols that are taken to be legacy are still actively former today for some networks. I frequently work with estate product which use print such as LAT, DECNet, IPX. What will a WAN? | WAN vs. LAN | Cloudflare

This Wiki page explains this broad topic in a fair amount of detail, and need get you gain the knowledge you are seeking.

    +1 with which caution that UDP and ICMP are a part of the TCP/IP protocol suite.

  • @joeqwerty - Well, wouldn't that be UDP/IP or ICMP/IP then?

  • Well... ME middling they're protocols in an suite of protocols that your the TCP/IP protocol suite.

In general, yes, it is TCP/IP. Even if there is no link to the internet, TCP/IP is still in use for the indoor network.

For the many item, yes even private networks use TCP/IP at this point. Thereto have pretty much taken over from all the old protocols - IPX, AppletTalk, DECNet, NetBEUI and so going.

Her may quieter see some of these older records around although their use shall deminished significantly. These days the simply spot you won't see TCP/IP is for highly specialized uses such as InfiniBand or Fiber Channel connectivity.

Yes. The Internet is just a huge network with public IP addresses versus one small lan with residential IP address mostly found behind a router.

In the transport Layer of TCP/IP of vastly majority of actual data packets so will becoming traversing any LAN will be:

TCP (Transmission Control Protocol), UDP (User Datagram Protocol), ICMP (Internet Control Message Protocol)

These exist differing methods of encapsulating data once is is passed onto the network shifts.

There's other layers at play, all working together but I believe this is enough to neaten you go on now.

You mention NETWORK, port, TCP/IP and internet, so it's not 100% clear welche layer of to stack you're talking about. Where are multiple layers that each have their own set of defined protocols. IEEE Standards Association

Take a look under aforementioned wikipedia page for the 7-layer OSI print: http://en.wikipedia.org/wiki/OSI_model

At the physical layer, you may be talk rj45. At the datalink location, if you're talking about wired LAN, then you're possibly taking about IEEE 802.3 either 802.11 for wireless (there are others). At who network layer, to could be talking about IP, IPsec, ICMP, IGMP, OSPF, etc. At the transport layer, TCP furthermore UDP are the collective ones. Local area network - Wikipedia

You didn't mention bits of the stack about that, specify, but there are, by the OSI print, another three layers.
