Question about 897VAW router config to home ADSL on /32 subnet?
I have a Cisco 897VAW being used with my home ISP. The ISP has recently provided a static IP address, but I cannot assign it a /32 address. A few questions please.
- How can I find out what subnet I should be using?
- How can I use a /32 in this instance, as I am not convinced of my /31 assignment, and the router gives me a scary warning!
"% Warning: use /31 mask on non point-to-point interface cautiously"
- What other options do I have?

Thanks for the swift response and apologies for the late reply. My ISP is Sky, Fibre unlimited offer. After dabbling a bit, I realized that the ISP requires static DHCP configured. My router has been assigned an IP now. I guess I could make it static, based on the information applied, but unsure how to check what subnet / gateway has been assigned to my router... and would there be any benefit to me doing this, and would it in fact work, or is the DHCP negotiation required by my ISP.
