Thread: what is static ip, how does it help

hi,

what is static ip, how does it help. do we have a static ip. I use bsnl ul750 with seimens c2110.

How does it very from a dynamic ip? Actually i had to send some newletters. I used a software with built in smtp server. some of the mails were rejected because of identifying as dynamic ip . i think hotmail does support this function. but using normal smtp server will have limitations to send mails. do you know any method to overcome this. like using regular smtp server for sending a bit large no of mails. .

dont mind if you are not aware. Simply help us all and give a picture of static and dynamic ips.

all the best

There are two types of ips...
The LAN ip and the WAN ip..
LAN ip is wat you get from your modem or router whereas WAN ip is wat you get from your service provider...
Furthur, LAN and WAN can be static or dynamic...
If you have just one system connected to your modem, then it will always get the same LAN ip 192.168.1.2( ofcourse u can make you system to get the LAN ip from 192.168.1.2 to 192.168.1.255, this is called making your ip static)..
In case you have more than one system, u wil get a random LAN ip each time u connect..
But WAN ip changes each time u connect to internet...

I don't clearly understand your particular smtp case but here's what static and dynamic ip's are:

If you have a static ip, then your ip will always remain the same. This is mostly used for hosting purposes or if someone wishes to have ssh, telnet etc to their machine over the internet. All this is also possible with dynamic ips but its a little messy(dyn dns etc). The bottom line is that you have a non-changing public ip. This is usually expensive, I don't know about bsnl but I think if you bought a normal plan it is most likely to have a dynamic ip. The ip 192.168.1.2(your machine) is static but it is not public, you cannont communicate with the internet or outside you own network using this. Usually your modem will Have NAT configured to translate this to a public ip, which is the dynamic ip provided by your ISP.

In case you have a dynamic ip, your modem/machine is automatically assigned an ip by your ISP using DHCP. It can be pre-configured by your ISP as to how long you should have one ip before your machine sends a request to obtain a new one. This is a public ip and can be used to communicate over the internet, but since it is dynamic, it will change after a time specified by your ISP.

There is nothing like LAN and WAN ips.
IP addresses are either private or public. Private ip's are used for internal networks and cannot communicate outside their networks, which means they cannot access the internet. Public ip's can communicate over WAN. both of these can either be static or dynamic. static wont' change, dynamic will. that's it!

Thank you. now i understand static and dynamic ips. see, i think our ip which others see will vary each time we connect to internet (please correct me if i am wrong). My question is, is it possible that someone can block emails from my ip. see i helped a friend. he need to send a few thousand mails. now i tried a few software for this. now i am afraid that some providers may block my email identifying the id. is it possible. let me repeat, i have a domestic bsnl ul750 connection and a normal desktop.

Also please tell me how can we get a US or Canada . it is possible. not to worry if you don't know.

I don't know how to get US or Canada !

If I don't know I try the search
engines like Google Yahoo etc.
But your query is so vague , I am not worrying!

see, it is possible to change your id(for ethical/legitimate needs). but needs some hands on exp.

It is quite possible that your ip be blocked (if these mails are sent from your ip) as a Spam site as you are sending so many mails within a span of few seconds (this is happening programatically). You must be aware of what your friend is doing. Unless you get all those email ids you cannot send them to all those ids.

Of course id can be changed very easily without any reason, if you wish, but I don't think for any legitimate purpose somebody does this

See, these spammers has make life difficult for ethical businessmen. Sending newsletter is almost impossible nowadays. emails from mathrubhumi( a prominent malayalam daily) are marked as spam. It happened to HBO, STAR and other providers who make legitimate use of it. HBO do not send mails directly. They assign someone to do it.

As the no. of users are more, they need to be strategised. Nowadays yahoo, google and hotmail detect ip to block mails. I know a lot of people who unknowingly fell victim to this. They simply tried to reach customers who opted for newletters. Also nowadays to access certain database located in Europe and US, you need specific ids(like one from that country).

There are a lot of ways to send bulk mail for registered purposes.
I've started running a blog. A simple wordpress plugin helps me send mails to subscribers. You should know where to host so that you dont fall in the cap put by hosting companies. you could also have a look at gmail for organisations and other providers.

Can you give some details. i am sure there are a lot of them out there who will benefit from that.

Most routers assign dynamic IP addresses by default. They do this because dynamic ip address networks require no configuration. The end user can simply plug their computer in, and their network will work. When ip addresses are assigned dynamically, the router is the one that assigns them. Every time a computer reboots it asks the router for an ip address. The router then hands it an ip address that has not already been handed out to another computer. This is important to note. When you set your computer to a static ip address, the router does not know that a computer is using that ip address. So the very same ip address may be handed to another computer later, and that will prevent both computers from connecting to the internet. So when you asign a static IP addresses, it's important to assign an IP address that will not be handed out to other computers by the dynamic IP address server. The dynamic IP address server is generally refered to as the dhcp server.
