From: Vwaju on 28 Jul 2008 16:47 I leased a static IP address from RCN (which has a telecommunications monopoly in our building). I have had difficulty configuring my network using this address, and I come to find out from RCN that it's "not truly static". I can't get a clear story from RCN about what this could possibly mean. It would seem that a domain name has to be mapped to a *permanent* IP address, and that an address is either *static* or it's *not*. (I am a residential customer of RCN, but RCN claims that the "not truly static" IP address they sold me is the same thing that they sell to business customers who are hosting their own web servers.) I don't want to spend any more time trying to configure my network until I get clear on whether my the IP address I'm paying $20/month for is *really* static or not. I would appreciate any insights into this question. Thanks & Best Regards, Vwaju New York City

Speaking for what I know about -- one example here -- I have a static IP, but it was dynamically allocated when I joined the ISP over four years ago. Since then the ISP changed wholesaler once, and my static IP also changed to a new IP block owned by the ISP. All I had to do was plug the new IP addr into my DNS service[1]. I have ADSL and have the modem running bridged mode into a linux box with rp-pppoe. So when I make a connection to the ISP I get told my IP addr, the first hop IP and given a pair of nameserver IPs. [1] As far as domain name goes, I use a free service (dyndns.org) which also allows dynamic IPs, there are notifier scripts around to update the DNS. Only problem here is I have the generic ISP reverse lookup, but that doesn't matter 'cos I don't do direct email to the world from firewall box. Sorry I've not been following this thread, but how do you connect to the ISP or service? If it's DHCP your machine should get all info required to connect (nameservers, first hop IPs) automatically.

Do they drop fiber or ethernet to your location? What? There's simply no way to answer this question without a few more details. - -- It is better to hear the rebuke of the wise, Than for a man to hear the song of fools.

I have a cable modem from RCN. I'm guessing the modem is proprietary and I don't know whether it is DOCSIS compliant. (I could find these things out). I assume that the cable service is fiber from RCN to the "head-end" and cable from the head-end to our apartment. (I'm going by Andrew Tanenbaum's "Computer Networks".)
