I get online using an ADSL line provided by Eircom.net. I use a Netopia Cayman 3341 as a router for my home network, and as a newbie to the world of in-depth networking, I’m completely lost.
I bought a block of for IP addresses from the same company (I think a block of four is called a /27 block?).
My problem is that every time there’s a power shortage, a machine crash, or even someone sneezes, my router resets and is given another IP address.
Every time my IP resets, I have to change the A record of my domain, and wait 8 hours for Eircom’s domain servers to update.
What’s bloody frustrating about this is that I have the technology! I own the IP block I want to link to my router!
At first glance, the Eircom.net support page is pretty complete.
When I dig a little deeper, though, suddenly everything’s fucked. I don’t use Windows or Mac, and the router is OS agnostic anyway.
My question is – how do I set up my router to have a static IP address? Even calling Eircom.net’s help line doesn’t help – they readily admit that they don’t know!
