where to buy public ip? which website
You get one form your ISP you can ask them but I doubt they will even consider it if you aren’t a company. Or a VPN might be a solution, I wouldn’t recommend
What are you trying to do ?
new node with new ip public but isp does not provide
Residential ISP’s generally will not hand out static or more than one IP per account. Generally if I wanted to have multiple single IP in separate /24 networks would require me to have a business account and deal with higher pricing.
IP addresses are given by ISPs, if you want a static one you can ask your ISP for for it, but it’s gonna cost money and it might be significant.
Set up Dynamic DNS and you won’t need a static IP.
where you live ? in Denmark it really no problem getting one and cost only 3,11 $
