i want to know that static and dynamic ip address which is better for seo point of view, please share some tips.

Static IP address do not change whereas dynamic IP changes.Mostly the ISP provides a dynamic IP and we have to request specially for a static one.We can find out whether we own a static or a dynamic byasking our ISP or visiting sites like Ip-details.com wherein we have to check after resetting our modem;if there is a change in IP then we have a dynamic IP and if the IP does not change then we own a static IP.
I feel the static IP is more useful in terms of SEO.Generally speaking having a website on a shared/dynamic IP address will not cause you any harm. You can rank good enough and there is nothing negative.So don't worry if you site is on it. It is just static IP's are more advantages than dynamic since it is dedicated for only you.

Thanks for providing this useful information.

A static IP address is essentially when you have your own IP address and it is dedicated to you only. This means that whenever you log into the internet you will be using the same IP address all the time, this can have positive implications for avid internet users. Dynamic IP address is constantly changing, the address will change every time you log in and out of the net.
