A
Anti-bot
antibot system
protection
Software systems that detect automated traffic: Cloudflare, Akamai, PerimeterX, Datadome, Imperva. They analyse headers, fingerprints, TLS handshakes, behavioural patterns. The harsher the anti-bot, the more expensive the proxy you need (residential/mobile instead of datacenter).
B
Bandwidth
billing
The volume of data transferred through a proxy. Measured in GB. Most residential providers bill per gigabyte ($1-10/GB); mobile dedicated ports usually bill per port without a bandwidth cap.
C
Carrier-grade NAT
CGN, CGNAT
network
A technology where a mobile operator allocates a single public IP to hundreds or thousands of subscribers. That's why mobile proxies are nearly impossible to ban — banning the IP would block thousands of real users. The key advantage of mobile proxies.
Concurrent connections
technical
Number of simultaneous connections through a single proxy port. Limits are typically 50-200 on residential, 10-100 on mobile. Going over results in throttling or timeouts.
L
Latency
performance
Delay from request to response through a proxy. Datacenter: 20-80ms, ISP: 50-150ms, residential: 100-500ms, mobile: 200-1000ms.
M
Mobile proxy
type
Proxies through real carrier SIM cards (Vodafone, T-Mobile, Kyivstar). Expensive ($25-45/month per port) but immune to bans thanks to carrier-grade NAT.
Multi-account
use-case
Working with many accounts on the same platform simultaneously (Facebook Ads, Instagram, bookmakers). Requires an anti-detect browser plus mobile dedicated proxies.
P
Port
technical
Numeric identifier for a proxy endpoint (1-65535). Standard ones: 80, 8080, 8000 (HTTP), 443 (HTTPS), 1080 (SOCKS5). On mobile dedicated, a separate port = a separate SIM.
T
Throughput
performance
Requests per second through one proxy port without degradation. Datacenter: 100+ rps, residential: 10-50 rps, mobile: 5-20 rps.
U
Unlimited bandwidth
billing
A plan without GB limits. Standard for mobile dedicated. In residential plans there's often a hidden cap on threads or concurrent IPs.
