Computer Network help...

pi3yeargrad · 08-11-2006, 10:05 AM

OK, I have a network at work and today made 2 computers use static IPs...the rest of the computers (mostly) are laptops that come in and out of the office....so Im wondering, do I have to set those computers up as well for static IPs? If I do set them up for static IPs will they (the people who own the computer.laptops) have to set up static IPs at their home networks as well? Can they keep the dynamic IPs and still connect at our work or how does that work?? I know if u keep some computers in the network using Dynamic IPs and others have Static IPs than there is the chance that itll interfere sometime and they (the dynamic) will not be able to get on the internet cuz 2 computers can not be running the same IP....will the router recognzie the 2 computers with static IP and not give out those IPs though???

You have to define a DHCP scope on your router. That means, you assign a block of IP addresses that it can assign as dynamic addresses.

My question is, why are you using static IPs? Firewall rules? The easiest thing is to just let DHCP handle it all.

From his prior posts, I believe the intent is to connect from his house to the static ip computers at his work.

What UWSkier said... what type of networking equipment is it? If its a simple store-bought router (eg. Dlink, Linksys, etc.) you can just log into the router to set the DHCP scope to not include the ones you want to use as static. To find the IP address of the router, just do an ipconfig and it's usually the same as your default gateway.

If you are on a corporate type network and you're using heavy-duty networking equipment (eg. Cisco routers, dedicated DHCP servers, etc.) you'll need the help of your IT dept. (if you have one).

Also, if you set those folks up to static on their laptops, when they connect to another network, they'll have to have their IP changed back to receice dynamic addresses.

ye, Im using the realvnc...I got everything working and noticed that the router assigns between .100 to .110 and never more...plus theres never usually that many computers connected at a time...SO I ended up just setting up the 2 static computers at like .125 and .126 so itll never (well hopefully, if im thinkin correctly) interfere with the dynamic IPs assigned by the router...

its just a smal office network...nothing to big (linksys router)

You should be fine with that then. However, when they take their laptops home and if they're not on the same subnet and gateway as you have at work, they won't be able to connect without changing them back to dynamic.

?? the 2 computers that I set up with static IPs are desktop computers that wont be leaving the office...so the other comps and laptops are still with dynamic IPs...I think this should work and I shouldnt have any probs no?

colding · 08-11-2006, 02:36 PM

Sorry... thought you said you were setting the laptops to static. Ya, in that case you should be good.

Keep the laptops at DHCP, the only things that are good for static are printers, and servers. If they take the laptops home and work, then they can use a PCMCIA card which has a WEP key on the back on the card. Considering that they have wi-fi at their homes, then they would need to add that WEP keep to the WAP (Wireless Access Point). They can usually call the provider of the router (more than likely it's a Lyksys), and they walk them through setting their WEP keys up on the WAP via their Interner Browser. The WAP has a static IP, and what that person would need to do is point his browser to the WAP, and add the WEP key and they should be off and running. I hope that's what you're asking... this is my type of work, so, if you have further questions, let me know.

*TexasTitan05* · 08-11-2006, 03:22 PM

....also, a lot of the newer laptops wireless is integrated. They can find the WEP key by typing 'ipconfig /all' at the CMD prompt. Hope this helps...

...I 100% agree with UW. When you hard code IP's (use static), you are setting yourself up for trouble later on down the line. Like I said, it's good to keep servers (which usually run DNS anyway - DNS to a hard coded static IP), and printers at static. I would ALWAYS use dynamic, and NOT static for desktops, and laptops. Now the DHCP doesn't handle the 'firewall rules', that's done at your internet server (usually around your Active Directory); so, I'm not sure what UW is trying to say here.

Hey TexasTitan...I think ur reading to much into my questions...lol...either way I was able to figure it out and I dont think I will have any probs...

I was just wanting to run realvnc on 2 computer in my office network (on 2 desktops that willbe staying on the same network at the office) I gave those 2 cdomputers static IPs that are up in the no zone for the router so they shouldnt interfere with the dynamic IPs givin by the router...

anyway thanks for the help and comments guys...

Ah, okay.... you want to run VNC. I still don't understand the logic of just keeping (2) desktops static. It's your network, and what you've done hasn't broken it. VNC is a nice tool to have !!!!

well I prolly dont know bout this stuff as much as u so my logic is prety basic...it worked and doesnt seem like itll give me a problem..I tried the port triggering to work on the 2 computers (those are the only 2 I really need to get some remote access too (but didnt work, kept having problems and could only use on one computer at a time even while configuring each computer working through different ports) so this was the easiest simplest way I could do it...
