IP address lookup

Type in an address, a prefix or an AS number. You get back the registry record, who is announcing the space, whether that announcement validates under RPKI, and where the geolocation databases think it is. These are the checks our brokers run before a block gets offered to anyone.

Try 8.8.8.0/24 or AS6206. Bare numbers are read as AS numbers.

Four checks will tell you whether a block is obviously broken. They will not tell you whether it is worth buying. Before we offer space to anyone we read its full routing history, scan every address in it against the blocklists, and find out what the reputation feeds still remember about whoever had it last.
