This unallocated address space is called the bogus space. Bogons also include reserved private address and link-local address ranges (Martian Packets). IANA might assign Bogon IP addresses to an entity or RIR with the passage of time. * * * ## Here are the bogon IP address ranges: * * * ## IPv4 Bogon Ranges | Netblock | Description | | --- | --- | | 0.0.0.0/8 | "This" network | | 10.0.0.0/8 | Private-use networks | | 100.64.0.0/10 | Carrier-grade NAT | | 127.0.0.0/8 | Loopback | | 127.0.53.53 | Name collision occurrence | | 169.254.0.0/16 | Link local | | 172.16.0.0/12 | Private-use networks | | 192.0.0.0/24 | IETF protocol assignments | | 192.0.2.0/24 | TEST-NET-1 | | 192.168.0.0/16 | Private-use networks | | 198.18.0.0/15 | Network interconnect device benchmark testing | | 198.51.100.0/24 | TEST-NET-2 | | 203.0.113.0/24 | TEST-NET-3 | | 224.0.0.0/4 | Multicast | | 240.0.0.0/4 | Reserved for future use | | 255.255.255.255/32 | Limited broadcast | * * * ## IPv6 Bogon Ranges | Netblock | Description | | --- | --- | | ::/128 | Node-scope unicast unspecified address | | ::1/128 | Node-scope unicast loopback address | | ::ffff:0:0/96 | IPv4-mapped addresses | | ::/96 | IPv4-compatible addresses | | 100::/64 | Remotely triggered black hole addresses | | 2001:10::/28 | Overlay routable cryptographic hash identifiers (ORCHID) | | 2001:db8::/32 | Documentation prefix | | fc00::/7 | Unique local addresses (ULA) | | fe80::/10 | Link-local unicast | | fec0::/10 | Site-local unicast (deprecated) | | ff00::/8 | Multicast (Note: ff0e::/16 is global scope and may appear on the global internet.) | * * * ## IPv6 Additional Bogon Ranges | Netblock | Description | | --- | --- | | 2002::/24 | 6to4 bogon (0.0.0.0/8) | | 2002:a00::/24 | 6to4 bogon (10.0.0.0/8) | | 2002:7f00::/24 | 6to4 bogon (127.0.0.0/8) | | 2002:a9fe::/32 | 6to4 bogon (169.254.0.0/16) | | 2002:ac10::/28 | 6to4 bogon (172.16.0.0/12) | | 2002:c000::/40 | 6to4 bogon (192.0.0.0/24) | | 2002:c000:200::/40 | 6to4 bogon (192.0.2.0/24) | | 2002:c0a8::/32 | 6to4 bogon (192.168.0.0/16) | | 2002:c612::/31 | 6to4 bogon (198.18.0.0/15) | | 2002:c633:6400::/40 | 6to4 bogon (198.51.100.0/24) | | 2002:cb00:7100::/40 | 6to4 bogon (203.0.113.0/24) | | 2002:e000::/20 | 6to4 bogon (224.0.0.0/4) | | 2002:f000::/20 | 6to4 bogon (240.0.0.0/4) | | 2002:ffff:ffff::/48 | 6to4 bogon (255.255.255.255/32) | | 2001::/40 | Teredo bogon (0.0.0.0/8) | | 2001:0:a00::/40 | Teredo bogon (10.0.0.0/8) | | 2001:0:7f00::/40 | Teredo bogon (127.0.0.0/8) | | 2001:0:a9fe::/48 | Teredo bogon (169.254.0.0/16) | | 2001:0:ac10::/44 | Teredo bogon (172.16.0.0/12) | | 2001:0:c000::/56 | Teredo bogon (192.0.0.0/24) | | 2001:0:c000:200::/56 | Teredo bogon (192.0.2.0/24) | | 2001:0:c0a8::/48 | Teredo bogon (192.168.0.0/16) | | 2001:0:c612::/47 | Teredo bogon (198.18.0.0/15) | | 2001:0:c633:6400::/56 | Teredo bogon (198.51.100.0/24) | | 2001:0:cb00:7100::/56 | Teredo bogon (203.0.113.0/24) | | 2001:0:e000::/36 | Teredo bogon (224.0.0.0/4) | | 2001:0:f000::/36 | Teredo bogon (240.0.0.0/4) | | 2001:0:ffff:ffff::/64 | Teredo bogon (255.255.255.255/32) | ### Related Articles [![Residential Proxy Detection: How It Works, Why It's Hard](https://blogs.ipgeolocation.io/blogs-site/content/images/2026/07/how-residential-proxy-detection-works-comp.png)](https://ipgeolocation.io/blog/how-residential-proxy-detection-works) [Residential Proxy Detection: How It Works, Why It's Hard](https://ipgeolocation.io/blog/how-residential-proxy-detection-works) Residential proxies make automated traffic look like real households, which is exactly why IP reputation checks miss them.

Private Relay is a Safari-only, two-hop privacy relay. WARP is a whole-device tunnel through Cloudflare's network. Both keep the user near their real region, and, as you will see below, our detection API flags both as relays. If you run a website, an app, or a fraud pipeline, you meet both of these in your logs, not in an app store.

The destination sees the proxy server's IP, not the visitor's. Here is how it works, whether it still matters, and how to flag the traffic.
