Another alternative, if you're simply looking for ASN/CIDR information, is
to use the routeviews project.

host -t txt 51.51.51.51.asn.routeviews.org

... returns the ASN and CIDR block of the IP in question.

Note that as usual, this is reversed dotted quad, so if your original IP is
1.2.3.4, you're querying 4.3.2.1.asn.routeviews.org

More information on the routeviews project: http://www.routeviews.org/

If you want information on the ASN, you can still query WHOIS.   Or you can
hit the CIDR Report:

http://www.cidr-report.org

Example:

$ host www.cidr-report.org
www.cidr-report.org has address 203.133.248.2

$ host -t txt 2.248.133.203.asn.routeviews.org
2.248.133.203.asn.routeviews.org descriptive text "4608" "203.133.248.0"
"24"

karsten at zharben:~$ host -t txt 51.51.51.51.asn.routeviews.org
51.51.51.51.asn.routeviews.org descriptive text "4294967295" "0" "0"
karsten at zharben:~$ host www.cidr-report.org
www.cidr-report.org has address 203.133.248.2
karsten at zharben:~$ host -t text 2.248.133.103.asn.routeviews.org
host: invalid type: text
