We are a registered company and have been working there for many years and are established employers. We recently re-vamped our website and will be using the same server in China to host the site.
We have an ICP number already but are concerned that even if we are using the same domain name, our IP address may change and this may invalidate our current ICP number. Do you think this will be the case?
Also, might we be granted a grace period if this is the case?
If so, how long might this be?

Thank you
