AS6830 is Liberty Global's primary European cable network ASN.

Liberty Global's network serves approximately 85 million customers across Europe.
Every time you visit a website, your IP address — and therefore your ISP (Liberty Global B.V.) — is visible to that site. Liberty Global B.V. as your ISP can see all unencrypted traffic passing through their network, including the domains you visit. This is standard practice for all ISPs and is typically used for network management, legal compliance, and in some cases targeted advertising.
If your device is assigned an IP in Liberty Global B.V.’s ranges, websites you visit will identify your connection as coming from Liberty Global B.V.. To prevent this, a VPN replaces your ISP-assigned IP with the VPN server’s IP, making your traffic appear to come from a different provider entirely.
AS6830 is registered with RIPE — the Regional Internet Registry responsible for IP allocations in Europe, the Middle East, and Central Asia. The ASN is used to announce IP prefixes to the global BGP routing table, allowing other networks to route traffic to Liberty Global B.V.’s infrastructure.
Liberty Global B.V. peers with major transit providers and internet exchanges to ensure global reachability. BGP peering relationships determine how traffic flows between Liberty Global B.V. and the rest of the internet.
