[modem/router] Static IP ? in Verizon Online DSL http://www.dslreports.com/forum/r12869940 en Sat, 05 Dec 2009 01:35:32 EDT Sat, 05 Dec 2009 01:35:32 EDT Re: [modem/router] Static IP ? http://www.dslreports.com/forum/remark,12885839 JohnA :

Some areas of Verizons network do not use dynamic IP addresses. In some parts of the ex-GTE areas the IPs assinged are static. But Verizon is coverting to all poppe.
You've got your terminology mixed up. All residential accounts use dynamic IPs, wether they are DHCP or PPPoE. Only business accounts use static IPs.]]> http://www.dslreports.com/forum/remark,12885839 Fri, 11 Mar 2005 11:38:22 EDT Re: [modem/router] Static IP ? http://www.dslreports.com/forum/remark,12885448 mc_365 : Some areas of Verizons network do not use dynamic IP addresses.

If you are paying them business rates for a static IP, then MyIP will confirm that the static IP you think you have is indeed the one your router is using to requesting web pages. You should not plug your router configuration to use a static IP unless you own the permanent rights to that public IP.

Verizon residential service uses dynamic IPs. They will issue you what you need when you need it. You have only temporary rights to it for only as long as you are actually using it. If you permanently plug your router with an address that is only temporarily yours, all hell will break loose when that address is reassigned to another user and now you are trying to convince the internet that both of you are the proper recipients of web page requests that are to be sent to that particular address.

The 192.168.x.x set of addresses is a completely unrelated set of addresses that apply only between your router and your computer system(s). Normally, your router will use an internal DHCP server to allocate those internal addresses as client systems turn on and off. It reserves 192.168.1.1 for itself, and then starts giving out addresses in sequence as needed, keeping them unique to each separate inside system, and recirculating the list as inside systems turn off.

The router performs what is called Network Address Translation (NAT) to translate the page request from internal system 192.168.1.101 (let's say) to the public address of aaa.bbb.ccc.ddd that was temporarily issued by Verizon to you. That packet goes out to where ever and the web page comes back to aaa.bbb.ccc.ddd and your router, knowing that inside system 192.168.1.101 has a pending request for something from that web page, it sends the page out through the network jack that it knows has inside system 192.168.1.101 on the other end of the cable.

If somebody on the outside sends an unsolicited request to aaa.bbb.ccc.ddd (your public address), your router will ignore it because it knows nobody inside asked for it. That's what a firewall is.

If you want to expose any particular inside system to outside requests, you have to assign it a static inside address in the 192.168.1.x range in a manner that will not conflict with any addresses that the router will be attempting to assign to other inside systems through its DHCP server. Typically that is done by configuring the router to 192.168.1.1 for itself and then setting the DHCP range to 192.168.1.100 and up. Thus inside addresses of 192.168.1.2 through 192.168.1.99 will never be assigned automatically by the router and you can manually assign anything you want to those addresses. For discussion, let's now say you have plugged your computer's network properties to use static internal address 192.168.1.75. In order for it to be exposed to the internet with unrestricted translation and pass-through of unsolicited external requests, you will need to configure your router with address 192.168.1.75 in the DMZ. Now anything coming in to aaa.bbb.ccc.ddd public address that was not previously asked for by a known inside system will be sent to ...75 without question. Now your friend should be able to SSH into that system - assuming that Verizon is not blocking the specific inbound ports that your friend's session might use.

WHen I had it in single static I use to connect to irc.freenode.net or irc.debian.org instantly, now when its in normal mode it takes about 20-30 seconds

(XChat, IRssi) this is irc on Linux by the way

I put it back to normal mode anyways since it seems more secured I still can see my ip (Actual) one when I go to www.myipaddress.com

Static means never changes.
From the ISP this usually cost extra.
You most likely have dynamic wich means it may change at anytime. It is however likely that it will not change very frequently. I have at times had the same IP for 20 days. This depends on the demand for IPs your use, if you power off your modem for any extended period of time you will probably lose your IP.

Single Static IP (Westell Lingo) means we will use a specific network connection to pass all wan side request to.
Single Static IP Enabled will pass traffic comming to your Public IP (from the ISP) to one of your network connection.

I would venture to say this setup would come in handy for configuring a server or proxy but I don't think its a good option for a home user. Any traffic that trys your public IP will be pass in to your pc if not properly firewall and locked down this could be bad.]]> http://www.dslreports.com/forum/remark,12870370 Wed, 09 Mar 2005 16:35:34 EDT Re: [modem/router] Static IP ? http://www.dslreports.com/forum/remark,12870218 RobNyc : So I think if I put it back to normal, I go to myipaddress.com I get the same so called static ip , I'll try now ]]> http://www.dslreports.com/forum/remark,12870218 Wed, 09 Mar 2005 16:21:10 EDT Re: [modem/router] Static IP ? http://www.dslreports.com/forum/remark,12870176 dick white : The router has the public IP that your friend is using to access your location. However, your router is not passing his "request" through the firewall to your system. The static IP that your system is using refers only to the internal private non-routable addresses used by the system(s) running behind your router. In order for your system to receive the external request from your friend, you must first set your system to a static IP (in the 192.168.x.x range) as you have, and then configure your router to put that system in its DMZ, namely fully exposed to the internet (including all the bad guys too).

And I see now I get an ip. BEcause before I was using the normal way and I was getting another ip which it was 192.168.x.x which is a router ip, and my friend was trying to ssh into my pc and he couldn't. Whats the difference if I have the ip in static mode or normal mode?
