Yea max man , its like that only. I have setup a Sify connection at a friend's place . He had an IP like 10.12.xx.xx and he had to specify a gateway address like 10.12.yy.yy
So as far as I can see , there is no public IP address. Infact I dont understand given the way SIFY login occurs, where is there a chance for it to assign an individual public IP address to your machine. What say people?? Is it possible that without using some kind of ppp protocol thingie, to assign individual public IP address??

Yup, its possible. In a dialup system, you have a CHAP handshake authentication, by which a user is authenticated. Once that is done, the user is assigned a public IP from it's available pool. Any traffic to that IP is then forwarded to you.
The same thing happens with Sify. You are authenticated with their SAM server. Upon successful authentication you are assigned a public IP and all traffic to that IP is forwarded to you using NAT.
Sify however does not forward traffic destined to some ports on your machine. One of them was port 80 (the last time I checked atleast). The reason for that is that the net service is for home use; home users cannot host a website from their homes. That is deemed as commercial use. Heck, using the internet more than 6 hours a day is commercial use according to their Terms and Conditions

Well thats ok...but when you use PAP/CHAP etc , the IP address assigned to your machine can be seen using commands like ipconfig / ifconfig . Hence we can say that the IP address is unique and assigned to your computer only . In SIFY , the dynamic IP address belongs to the Gateway and _not_ _ your_ _computer_ . So anyone else on the same LAN using same Gateway also gets the same Global IP address. So its not a unique public IP address. Its just like your plain old Internet Connection Sharing kinda thing.The SAM server thing is just a Database Thing AFAIK, used to monitor accounts and store account info.

No, it's not the gateway IP address, and computers on the network don't get the same IP address. They provide a unique public IP address to you at every login, just like with dial-up.
And the SAM system (not just the auth server) is not just a database that does some elementary account management. It does a whole lot of other things as well, like IP address assignment, bandwidth allocation on login, etc.
yakity yakity yak...and the outcome? No Sify connections cannot be used to host webservers![/b]
Wrong, you can most definitely use your public IP for your webserver. Check out this site:
http://siddhesh.no-ip.info
I host this site on one of my systems at home. There are free services like No-IP, DynDns, etc. that detect your public IP and you can assign a subdomain name (siddhesh.no-ip.info in my case) to redirect to your computer. They also provide programs that run periodically to update the public IP address on their servers so that the connection doesn't fail.
But do note that they no longer forward traffic on port 80. You'll have to host the site on another port. I host mine on 9880.

Excuse me, the last time I checked the port to host your website was 80 and not 9880 So you not only need a dynamic DNS service but also a port redirect which sucks! 
[/b]
Yes, you _generally_ host your site on port 80. It's not a rule though. For a hobbyist, any open port should be OK to host his personal site. If you want visibility then submit your URL to google and they're gladly index and rank you (provided you stay online consistently). For someone hosting a production website, get a static IP. Sify will gladly give you one for a price.
Dynamic DNS services also provide a port redirect. Check out No-IP's services for example. I'm using that. It doesn't cost a penny.
Blocking of port 80 is still a bit silly though. I think it's yet another silly, half-baked "security measure" by Sify.

Siddesh, its not a half baked security measure. It's a perfectly well thought strategy to keep people from hosting commercial websites on thier connections. If I had a faster connection then I would've probably started shared hosting for lowend websites. I already have a 24x7 server running. Only my ISP should co-operate in terms of uptime and affordable pricing on their speeds. And no. It's not for commercial purposes. It's simply a hobby. Well, atleast my ISP doesnt block ports

I don't think there's anything wrong/evil in their strategy of blocking port 80 access. And if you're a hobbyist I don't think you should care what port your site runs on. Sify is co-operating with competitive prices on their speeds, large variety of packages and so-so uptime (sucks in the rains).
And good for you that you're ISP doesn't block port 80. Not so good for all the zombie machines on your ISP's network that have IIS pre-installed and are serving as spambots relaying "free pr0n and v14gr4" emails. I had done "tests" of that kind on some machines on my network sometime in the past sending myself "you're st000p1d!!!!!!!!!!11oneone" emails .
*Sigh* those were good days

Hi guys it is possible and i've dont it alot of times. i had some webserver which i used to run on LAN and also on internet through www.no-ip.com and there u need to run a program which updates the dynamic ip address automatically. u need to be online all the time for that. and u can see that ip(your dynamic) address on the website also.
and also u need to redirect your port 80.
tested and works fine. infact was working fine till last april may. now i've stopped that server.
