One per independent network that it is connected to.
For example a computer connected to two ethernet networks (via different adapters) and to a wi-fi network will have 3 different IPs assigned: one for each net.
It is more typical for a computer to be connected to only one network at a time, in which case it would never have more than one IP assigned.
The number of available addresses is only limited by the current IP technology in use. We are currently using IPv4, which allocates 4,294,967,296 (232) possible unique addresses. In the next few years the internet will be migrating towards IPv6, which uses hex characters for each octet as opposed to numerical. In theory using IPv6, there would be exactly 2128, or about 3.403 × 1038 unique host interface addresses. Although just as we are upgrading IP technologies now, this number will one day not be enough.
Writing for Technology Review in 2004, Simson Garfinkel wrote notes that there will exist "roughly 5,000 addresses for every square micrometer of the Earth's surface".
I'm going to assume we're talking about IPv4, not the new and not-implemented-everywhere IPv6.
an IPv4 address consists of four bytes (8 bits each, 256 possible values per byte) generally written in decimal as, for instance, 192.168.1.255. so if every possible combination of values was legal, there would be 256*256*256*256 (4,294,967,296) possible addresses.
however, the first byte of an IPv4 address is limited to the values 1-126 and 128-223, so there are 222*256*256*256 (3,724,541,952) legal addresses.
there are also ranges of addresses that are considered "private subnets," and exist only behind routers (off the internet proper). for example, the 65536 addresses in 192.168.x.y cannot exist on the internet proper, but they're what you'll find in your office, school, or home LAN. there can be many, many 192.168.x.y subnets, each fronted by a "real" IP address assigned to a router, which makes all machines on the local subnet appear at the same internet IP address. the router connecting your LAN to the internet uses something called NAT (network address translation) to make the devices on your LAN believe they're actually on the internet. addresses 10.x.y.z and 172.16-31.x.y are similarly reserved for private networks.
I'll leave the math to you - subtract the 192.168.x.y, 10.x.y.z, and 172.16-31.x.y addresses from my previous number and that should be the number of "real" addresses on the internet, minus those reserved for local networks.
the above should be pretty accurate, but I'm a software engineer, not a network god.
if by address, you mean street address, then every street address that pays for internet access through an isp has an ip address.
Each address can only be used once at any given time.
Since IP4 uses 32-bit technology, the maximum number of possible addresses is 4,294,967,296
about 16 million

Only one ip address to be registered on the internet, which is normally fixed by your isp provider
The IP address identifies a server in a network and to the internet in the IP protocol. (IP means Internet Protocol) Many important communication protocols rely on the IP protocol. You are reading this message from the internet, so your computer has an IP address. The IP address for your home computer is assigned by your ISP (your service provider). It is usually dynamically assigned when your modem connects to the network. To view your IP address on a windows server, get a command window (Start > run > type "cmd") and type the command "ipconfig".
the IP address is assigned to your computer by your DHCP server you can only have 1 true ip address, although you can have ghost ip address and private ip addresses Private Addresses are not routable through the internet Ghosts IP addresses are normally used to cover something up, usually something illegal ;)
There are thousands upon thousands of IP addresses. Each Internet Provider is assigned a range of numbers. One gets assigned to you EACH time you enter the internet (or one of your programs accesses the Internet). That IP stays for that session. You may have the same IP hundreds of times--but then, get switched to a different one.
Internet Ip address is number which is assigned to a computer which are connected to a Internet.We can find the Details of that Ip address using free online sites like Ip-Details.com.Domain names are the names which are used to identify a website.It is assigned to left side of the Domain Extension.For Example in Google.com Google will be a domain name.Domain name is very important for an website.You can register a domain first to create a website.There are many online sites like Tucktail.com.XnYnZ.com,Thewebpole.com to Register a domain name...The main requirements of internet connection is modem,Telephone connection and computer.....

As many as you like.
The three distinct and worldwide unique identifiers for business computers are typically the MAC address (Media Access Control), the IP address (Internet Protocol), and the hostname (assigned name to the device on the network).
NONE because server is always assigned static IP address. server can have as many IPs as many network cards usually 2 are assigned one for normal working and one for ILO in case of emergency

Are you sure you mean switchport? IPs aren't assigned to a switchport. They can be assigned to switches. When an IP is assigned to a switch, it's permanent. They are also assigned to computers, usually by a DHCP server, which has a lease period, but that can be set to many different lengths.
