Known problems

  • Not all countries have a whois server. Sometimes because I don’t know, but usually because there simply isn’t any.
  • Some whois servers have a limit to the number of queries per day. They look at the ip-address of the computer making the query. This script is running on a server with a fixed ip-address, so when it’s used a lot it may trip a limit.
  • The output can be difficult to read for novices. It’s a big pity that Whois data is not standardized and therefore cannot be easily reformatted.
