	+ It's generally impossible to determine the location of a given user with any degree of certainty or granularity.

Services from the big megacorps (e.g. ATT, Comcast) give more geographically accurate info in reverse DNS, but even then it's not very close to home - e.g. someone in Davis may show up as being in Sacramento, except when they show up as being in Los Angeles (as they sometimes do.) + + Also, many ISPs outsource critical components of their dialup modem service to a company based in San Jose, so anyone using such a dialup service anywhere in the state will appear to be from San Jose. + + If you'd like to experiment, here is a free IP address geolocation tool: http://www.hostip.info/ + + Using the HostIP.info geolocation tool, one of the authors of this article found the following: + + ''My current IP address shows as close to home (Oakland) as one can reasonably expect - it says that I'm in San Francisco.

- ''Shouldn't most of this should probably be a simple pointer to http://en.wikipedia.org/wiki/IP_Address?'' - - IP addresses in use on the Internet are assigned in blocks to registrants by the [http://www.iana.org Internet Assigned Numbers Authority (IANA)] and its regional associates. Every machine that uses a Transmission Control Protocol/Internet Protocol (TCP/IP) network has an IP address. Examples of TCP/IP networks include: - LANs (local area network) (When you shared your printer between multiple household computers, you're using a LAN. Each computer or other network-connected device, which these days can include video game systems such as the XBox, has its own IP address.) - WANs (wide-area network) (the Internet is the best example of a WAN) - - This address is a 32-bit quantity, written as a ''dotted quad'' - groups of four ''octets'' seperated by periods, in the format of xxx.xxx.xxx.xxx. Each xxx may range from 0 to 255. Leading 0s are omitted. For example, 82.165.250.53 is the current address of www.daviswiki.org. Originally, networks were sized as class A, B, and C. This proved to be overly restrictive as the Internet (then [wiki:WikiPedia:Arpanet Arpanet]) grew. Nowadays [wiki:WikiPedia:Classless_Inter-Domain_Routing Classless Inter-Domain Routing] (CIDR) format is used, this is the xxx.xxx.xxx.xxx/xx notation. The first part is the network number and the /xx denotes that the first xx bits are used as the network address, while the remaining bits are the host portion of the address. For instance, 169.237.0.0/16 is assigned to UC Davis. Alternatively, this can be represented as a netrange (i.e. 169.237.0.0 - 169.237.255.255). - - IP addresses may be either static or dynamic. If you have the same IP address every time you connect to the Internet, you have a static IP. If you have a different address every time you connect to the Internet, you have a dynamic IP. This would be roughly analogous to your phone number changing every time you use the phone. Internet providers charge more for static IP's because they cannot oversell them (that is, sell access to more users then they have available IP addresses), and have more administrative overhead. Depending on your service, your dynamic address may be static for months at a time, or change every time you are away from your computer for a few minutes. Dynamic addresses must be assigned in an orderly way to prevent two machines from trying to use the same IP address. This is usually done by either Dynamic Host Configuration Protocol (DHCP) or Point to Point Protocol (PPP). - - The above text refers to '''[wiki:WikiPedia:IPv4 IPv4]''', which is slowly being superceded by '''[wiki:WikiPedia:IPv6 IPv6]'''.	+ A full, in-depth explanation of IP Addresses can be found [wiki:WikiPedia:IP_Address at Wikipedia]

I think it has long since been replaced by DHCP for that purpose. In this context it would not go across networks either.

It would make sense for most hosts not to reply to it because according to TCP/IP Illustrated and RFC-1122 section 3.2.2.9 , it was orginally for use when a host that is not statically configured is booting, and the request would be broadcast. I think it has long since been replaced by DHCP for that purpose. In this context it would not go across networks either. The RFC also says that hosts should only respond to type 17 requests if they are specifically configured as "Authoritative Agents". So I'm really curious what you did and why DCN would have their servers configured this way.

- Every machine connected to the Internet (WAN) has an IP (Internet Protocol) address. This address is a 32-bit quantity, written as four ''octets'' (bytes) in the format of xxx.xxx.xxx.xxx. Each xxx may range from 0 to 255. For example, 82.165.250.53 is the current address of www.daviswiki.org. Originally, networks were sized as class A, B, and C. This proved to be overly restrictive as the Internet (then Arpanet) grew. Nowadays CIDR format is used, this is the xxx.xxx.xxx.xxx/xx notation. The /xx is the number of bits which are used, for instance 169.237.0.0/16 is assigned to UC Davis. Alternatively, this can be represented as a netrange (i.e. 169.237.0.0 - 169.237.255.255). Avoid ".xxx" notation, as it's ambiguous when the networks do not fall on even /8, /16, and /24 sizes.	+ Every machine that uses a TCP/IP network has an IP (Internet Protocol) address. Examples of TCP/IP networks include: + LANs (local area network) (When you hook up your XBoxen together and play Halo 2, you're making a LAN of XBoxen. Each XBox has its own IP address) + WANs (wide-area network) (the Internet is the best example of a WAN)

- There are two types of IP addresses: static and dynamic. A dynamic address is the equivalent of having a telephone "party line", back in the early days of telephone service. It is a shared address; others may use it when you're not. Providers charge more for static IP's, because they can. Depending on your service, your dynamic address may be static for months at a time, or change every time you are away from your computer for a few minutes. Having a dynamic IP address makes it difficult for others to connect to you (imagine if you're phone number changed every time you called someone). Web servers (almost) always use static IP addresses.	+ This address is a 32-bit quantity, written as a ''dotted quad'' - groups of four ''octets'' seperated by periods, in the format of xxx.xxx.xxx.xxx. Each xxx may range from 0 to 255, leading 0s are not used. For example, 82.165.250.53 is the current address of www.daviswiki.org. Originally, networks were sized as class A, B, and C.

Avoid ".xxx" notation, as it's ambiguous when the networks do not fall on even /8, /16, and /24 sizes. + + There are two types of IP addresses: static and dynamic. If you have the same IP address every time you connect to the Internet, you have a static IP. If you have a different address every time you connect to the Internet, you have a dynamic IP. This would be roughly analogous to your phone number changing every time you use the phone. Internet providers charge more for static IP's because they can. Depending on your service, your dynamic address may be static for months at a time, or change every time you are away from your computer for a few minutes. Dynamic addresses must be assigned in an orderly way to prevent two machines from trying to use the same IP address. This is usually done by a service called 'DHCP'

Just as every Internet terminal has an IP address, every Ethernet terminal has a MAC address (AKA physical address). These are 6 bytes, usually listed as aa:bb:cc:dd:ee:ff. The first three bytes (aa:bb:cc) are assigned by the IEEE to the manufacturer of the NIC, the last three are assigned by the manufacturer. I have found it very useful to keep a list of these for my own use. The IEEE maintains a public list of these. These are only visible on your LAN, that is, they are not accessible over the Internet.
