Miner IP Address
An IP address is the asic's number on the network. You open the ASIC's web interface at that address, where hashrate, temperatures and pool settings are visible.
What a miner's IP address is
A fresh ASIC gets an address automatically by default, over DHCP: you plug it into the router and the router hands out the first free number. Then you open that address in a browser and land in the miner's web interface.
The trouble with automatic assignment is that the address changes. After a router reboot the asic can get a different number, bookmarks stop working, and monitoring systems lose sight of it. That is why addresses at a site get pinned down, either as a static address in the miner itself or as a binding to its MAC address in the router.
The easiest way to find an asic you have lost is the address lease list on the router: it shows every connected device and its name. The second way is a network scanner that walks a range and shows what answers on the web interface port.
The address is needed only inside your own network. Nobody publishes an ASIC to the outside: a web interface with a factory password on the open internet is a gift to strangers. The link to the pool runs on outbound connections over Stratum and needs no forwarded ports.

How to get your addresses in order
Give the asics addresses that make sense and write them down next to the worker names. When garaje-03 goes quiet in the pool, you should know in a second which address to open instead of scanning the network all over again.
Pinning is better done on the router than in the miner: when an ASIC gets swapped you fix one record instead of hunting for where the old static address was set. And the asic's firmware then keeps its factory network settings, which makes diagnostics easier.
Change the factory password on the web interface. Even inside a home network this is sensible: any device on the same network sees the asic, and factory login and password pairs are known to everyone.
Example
Three asics in a storage room: we pinned their addresses on the router and wrote them in a table next to the workers trastero-01, 02 and 03. In the morning the pool shows zero on the second one: you open its address, see hashrate down on one hash board and know right away what to bring to the workshop.

Questions and answers
How do you find an ASIC's IP address
The easiest way is the list of connected devices on the router. The second option is a local network scanner: it will show which addresses answer on the web interface port.
Do you need a static address
On a single asic you can live with an automatic one. At a site it is better to pin them, or monitoring loses miners after a router reboot.
Can you log into an asic from the internet
Technically yes, but there is no need: an open web interface with a factory password gets broken into fast. For remote access people use a secure connection into their own network.
