Answer 1

For most of the things on your internal network you are better using a dynamic address. The difference is that one does not change when you disconnect or reboot and the other can. Some things might need special configuration (port forwarding for instance) and then they are better with a static address. The disadvantage of a static address is that it can overlap with another dynamic ip and cause confusion unless you configure it carefully to be well away from the dynamic block of numbers. But a correctly set up static address should not have become dynamic on a reboot. Take a look to see what you did wrong if it needs to be static.

Answer 2

Well, Dynamic IP address are prone to error, because, they're Dynamic! It means that the IP address can change, so, it means the DNS (Domain Name Servers, the things that convert a website name into an IP Address) has to be updated.

Answer 3

If you're running a server locally, and a router, you use a static internal address for the server. You can use either for the client, since nothing is connecting to it, so nothing needs to know its address.



Yes, dynamic is "automatically get" or dhcp, static is an address you type in. A static address has to be the same first 3 number sets (octets) - 192.168.1 - or whatever your router uses, and the 4th octet has to be outside the DHCP range of the router. (So if the router's dhcp server is giving out 192.168.1.100-192.168.1.254, you'd use something in the range of 192.168.1.2-192.168.1.99 [the router itself would be 192.168.1.1].)

Answer 4

static= address stays the same, dynamic, means it changes.
