Are you using Internet Service Provider (ISP) service that provides static IP? That means, particular IP address solely be used by you and no other users can use your IP. Whereas dynamic IP is similar to a tube that has arrays of IP from top to bottom and users who connects to Internet will use the first free IP in the stack to obtain connection. For dynamic IP, if the connection resets or re-connects, you won’t get the same IP connection as earlier because you will obtain next free IP in the IP tube arrays. In simple words, users with dynamic IP ISP services often shares IP. It is good to have our own IP address that represents us uniquely, but it is not helpful if you are in SEO field like link building.
If you are offering link building services or other SEO services where you need to search hundreds of queries using Google; for example to check your website ranking for several keyword phrases or check indexed pages in Google.com or Google.co.uk or other datacenters. There are more queries required to be made using Google search engine to obtain site wide analysis for any client. More queries can get you banned from searching Google again. I often get this limitation too and even if I clear the cache and cookies, I still won’t be able to do a normal search using Google. It forces me to disconnect my Internet connection and make a new connection (which obtain new IP because I’m using dynamic IP services) that allows me to do search.
Google have advice us on all the search queries but using it several time can get us banned too. If you are in this field, you should already face this problem more than once a day. There are cases where dynamic IP is useful too even though it is cheaper than getting a static IP. Most businesses will try to get static IP instead dynamic and it is costly too. With growing security measurements installed in major applications online, slight difference or excessive usage can lead banning. Static IP users might have to wait several hours or days for the penalty to be revoked. There you go with one disadvantage of using static IP over dynamic IP. Now, can you add more list of disadvantage using static IP?
