It is best to use a fixed IP address

This is because the broadband we normally use uses floating IP addresses, and floating IP addresses have a certain risk of being associated. You should know that Amazon does not allow sellers to open multiple accounts on the same Amazon site. If discovered, sellers will be required to delete the redundant accounts. At the same time, the IP address is an important factor used by Amazon to determine whether multiple stores are operated by the same person. Therefore, once the IP address is used by multiple accounts due to changes in the IP address, it will be associated, thus affecting the normal operation of sellers.
