AS701 is Verizon's primary ASN for its internet backbone and consumer/business services. Verizon is the largest wireless carrier in the US and one of the largest Tier-1 internet providers globally. The 4.0.0.0/8 block — one of the earliest Class A allocations — belongs to Verizon and is seen across the internet as both end-user addresses and backbone infrastructure.
Every time you visit a website, your IP address — and therefore your ISP (Verizon Communications) — is visible to that site. Verizon Communications 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 Verizon Communications’s ranges, websites you visit will identify your connection as coming from Verizon Communications. 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.
AS701 is registered with ARIN — the Regional Internet Registry responsible for IP allocations in North America. The ASN is used to announce IP prefixes to the global BGP routing table, allowing other networks to route traffic to Verizon Communications’s infrastructure.
Verizon Communications peers with major transit providers and internet exchanges to ensure global reachability. BGP peering relationships determine how traffic flows between Verizon Communications and the rest of the internet.
