They're all identical. The whois protocol is stupid simple; here's the |
| 13 |
entire spec from the RFC: |
| 14 |
|
| 15 |
2. Protocol Specification |
| 16 |
|
| 17 |
A WHOIS server listens on TCP port 43 for requests from WHOIS |
| 18 |
clients. The WHOIS client makes a text request to the WHOIS server, |
| 19 |
then the WHOIS server replies with text content. All requests are |
| 20 |
terminated with ASCII CR and then ASCII LF. The response might |
| 21 |
contain more than one line of text, so the presence of ASCII CR or |
| 22 |
ASCII LF characters does not indicate the end of the response. The |
| 23 |
WHOIS server closes its connection as soon as the output is finished. |
| 24 |
The closed TCP connection is the indication to the client that the |
| 25 |
response has been received. |
| 26 |
|
| 27 |
Different data are located in different places, though. So if you're |
| 28 |
looking up an IP address, you'll want one server. If you're looking up |
| 29 |
an AS number, you'll want another. All the client does is run |
| 30 |
heuristics to figure out who (and how) to query. Then it dumps it to a |
| 31 |
terminal. |
| 32 |
|
| 33 |
In short, there are a lot of whois clients for the same reason there |
| 34 |
are a lot of telnet clients: it's something you can sit down and write |
| 35 |
in a weekend. |
| 36 |

Personally, I tried jwhois at first, but couldn't remember to type the |
| 38 |
'j'. So now I use non-j whois. |
