whois multiple domains

• Produces a list of when your domains expire

  Create a text file called domainlist.txt with a domain per line, then run the command above. All registries are a little different, so play around with the command. Should produce a list of domains and their expirations date. I am responsible for my companies domains and have a dozen or so myself, so this is a quick check if I overlooked any.

  This is sample output - yours may be different.

• List contact infomation for Domain list

  Nice neat feedback showing contact infomation for as many domains as you wish to feed it. I used a list of domains, each one on a new line as supplied by our registar, as we needed to check they were all upto date and back them up as we are updating them all.

  This is sample output - yours may be different.

• Query ip pools based on successive netnames via whois

  Useful if you f.i. want to block/allow all connections from a certain provider which uses successive netnames for his ip blocks. In this example I used the german Deutsche Telekom which has DTAG-DIAL followed by a number as netname for the dial in pools. There are - as always ;) - different ways to do this. If you have seq available you can use net=DTAG-DIAL ; for i in `seq 1 30`; do whois -h whois.ripe.net $net$i | grep '^inetnum:' | sed "s;^.*:;$net$i;" ; done or without seq you can use bash brace expansion net=DTAG-DIAL ; for i in {1..30}; do whois -h whois.ripe.net $net$i | grep '^inetnum:' | sed "s;^.*:;$net$i;" ; done or if you like while better than for use something like net=DTAG-DIAL ; i=1 ; while true ; do whois -h whois.ripe.net $net$i | grep '^inetnum:' | sed "s;^.*:;$net$i;" ; test $i = 30 && break ; i=$(expr $i + 1) ; done and so on.

  # net=DTAG-DIAL ; for (( i=1; i<30; i++ )); do whois -h whois.ripe.net $net$i | grep '^inetnum:' | sed "s;^.*:;$net$i;" ; done
  DTAG-DIAL1      62.224.0.0 - 62.224.127.255
  DTAG-DIAL1      62.224.128.0 - 62.224.255.255
  DTAG-DIAL2      193.158.128.0 - 193.158.191.255
  DTAG-DIAL3      193.159.0.0 - 193.159.158.255

whois servers have strict limits concerning too much request on a short period of time. This command will certainly lead to get your IP blocked temporarely in the whois server after a few requests.
