This table only shows the first 100 of the set of IPv4 and IPv6 prefixes. All data is available via our IP data API.
IP ranges are the different blocks of IP addresses advertised by an Autonomous System (AS). These ranges can be used by the same organization operating the AS, or by different organizations.
AS4766 peers with these other Autonomous Systems.
Peering is a direct, often free, traffic exchange between Autonomous Systems (ASNs). They share routes only to their own networks and customers, making connections faster and cheaper for that specific traffic, without providing full internet access to each other.
AS4766 provides internet connectivity to these downstream Autonomous Systems.
A downstream is a customer Autonomous System that pays another AS (its provider) for internet access. The provider AS carries the downstream's traffic and makes its network reachable.
Discover your public IP address and detailed information about your connection.
Convert CIDR notation to IP address ranges and vice versa. Useful for network configuration and security.
Perform a reverse DNS (rDNS) lookup to get the hostname for an IP address.
Expand or collapse IPv6 addresses to their full or shortened forms for better readability and usage.
