Assign static IP with direct cable into modem (no router)

Hi Experts;
Here's my configuration:
1 PC (win 7) cabled directly into a DSL modem.
I want to make my IP static.

I've set the IP with properties on Local network connection; IPv4 ~ but when I validate the connection the Windows Network diagnostics t-shooter wants me to enable DHCP, which undoes my static settings.

No router involved.
Attached are screen shots of properties before & after I change settings.

Geisrud makes a good point. We were assuming that you purchased a static address from your provider, but can you confirm whether this is the case?

Thank you everyone.
I had not purchased a static IP from my ISP. I have a call into them now.
The subnet mask was set to 255.255.255.0 but it wasn't in the graphic.

One other question, If I go w/ the static IP; is my system at high risk of attack?

The link i posted answers this question

Also, that mask most likely would not have worked either way. You were assuming the address had a 24 bit mask.

Thanks again all.
We've decided against the static IP. I appreciate the information from all of you.

You can use a service to make a dynamic IP function like a static via a hostname,
