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.
AS133119 has no peers recorded.
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.
AS133119 uses these Autonomous Systems as its upstreams.
An upstream (or transit provider) is another AS that AS133119 pays for full internet connectivity, allowing it to reach all global destinations and be reachable by them.
AS133119 has no downstreams recorded.
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.
