Help - Lookup an IP Address

Addresses can be entered by using the input boxes (Single / List) or by passing them as parameters in the URL:

Any punctuation character can be used to split the addresses except '.' (dot) and ':' as these characters are used in the addresses themselves.

IP addresses can be entered in either IPv4 or IPv6 address format:

IPv4 decimal (quad-dot standard notation)
IPv4 hexadecimal (numbers must start with '0x')
IPv4 octal (numbers must start with a leading 0)
IPv4 binary
IPv4 long (a single decimal number)

(All IPv4 address numbers must be expressed in the same base)
IPv6 (compressed or uncompressed)
IPv6 "IPv4 compatible"
IPv6 "IPv4 mapped"
IPv6 6to4
IPv6 ISATAP
IPv6 teredo
