Choosing Proxies for Platforms in Afina: Astro's Guide

A team managing dozens or hundreds of social accounts eventually hits the same wall: profiles that looked clean yesterday suddenly start collecting verifications, request limits, and restrictions. On the browser side, everything may look fine. Fingerprints are isolated, profiles are saved, cookies are clean. The problem sits at the network layer. And when something breaks in the workflow, the cause is rarely one single mistake. Almost always it is a mismatch between the proxy you use and what the platform expects. For LinkedIn, a residential IP that jumps on every request looks suspicious. Instagram is wary of datacenter IPs. And one mobile IP, shared across dozens of profiles, is disliked by almost every platform.

This guide explains how to choose proxy type and rotation mode for each platform and task inside Afina, and where Astro fits as the network layer.

Why the result depends on the network layer

Platforms read an account on two levels. The first is device identity, what the browser shows: fingerprints, storage, profile history. Afina handles this layer. The second is network identity, what the IP shows: ASN, geolocation, carrier or hosting class, and rotation behavior itself. When both levels read as "different people in different networks," profiles live separately from each other. When they do not, accounts get linked, and clean cookies or separate logins will not fix it. The gap only grows with scale. A hundred profiles on a few IPs, or addresses that change in the middle of a session, do not look like real users. This is the typical root cause when blocks hit entire clusters at once.

What Astro takes on

Astro is proxy infrastructure that gives each profile and worker in Afina a network identity. There are three proxy types: residential, mobile (4G/5G), and datacenter. Its role in the workflow is narrow but critical:

• give each profile a clean address that does not overlap with others;
• route traffic through the network type expected by the specific platform;
• control when and how often the IP changes;
• maintain stable bandwidth when many workers run at the same time

The types differ by trust and price. Mobile has the highest baseline trust: carrier IPs are shared by many real subscribers, and platforms are reluctant to block them. Residential proxies are used as the daily workhorse. Datacenter proxies are the cheapest and fastest, but their hosting ASN is detected immediately.

Practical use cases

Multi-accounting in social networks (Instagram, TikTok). Large numbers of app-oriented accounts work on mobile 4G/5G. These platforms expect exactly this connection profile, so the risk of linking accounts together drops.

Outreach and brand presence (Facebook, X, LinkedIn, YouTube). Logged-in accounts at volume are kept on residential IPs using the "one profile, one IP" model so they remain isolated.

E-commerce and marketplace operations. Storefronts and regional accounts are placed on residential IPs with city targeting so the address matches the declared location.

Bounty and airdrop. Large sets of Web3 profiles sit on residential IPs, and at sensitive steps switch to mobile so wallets and accounts do not get linked.

Scraping public data and competitors. Prices, listings, and SERP results are collected on datacenter IPs with rotation on every connection. High volume at minimal cost.

Ad and SERP verification. Creatives and search results are checked across regions with city and provider targeting, so traffic exits exactly where it should.

Account recovery and verification. For 2FA and repeat logins, mobile IPs with manual rotation are used so the address stays stable and trusted during sensitive steps.

Astro and Afina: how they work together

Afina is an antidetect browser and workspace for profiles, accounts, tasks, and automation. The two products meet exactly at the points that matter for connected workflows:

One port, one profile. Individual Astro ports do not overlap between users, mirroring Afina's profile isolation principle.

SOCKS5 for Afina's UDP channel. Afina sends UDP over SOCKS5 (QUIC / HTTP/3) through the real proxy IP. SOCKS5 support in Astro keeps this traffic on the proxy instead of letting it bypass it.

Rotation through API. Astro rotation can be managed through API, so it is easy to embed into Node.js modules and Afina triggers instead of manual settings.

GEO for mass profiles. City and provider targeting allows regional accounts created in bulk through Afina to send traffic exactly where needed.

Proxy type and rotation by task

Use this as a starting point for each task in Afina, then adjust based on actual metrics.

The logic is simple: the more sensitive a platform is to mobile traffic, the closer you stay to mobile 4G/5G, and the more massive and impersonal the task, the more datacenter IPs with frequent rotation make sense.

Astro: facts and numbers

To gauge scale and cost, it helps to gather Astro's key specs in one place. Here are the core numbers on the pool, protocols, and pricing.

• Pool: 50M IPs in 150 countries, residential, mobile (4G/5G), and datacenter;
• Protocols: HTTP(S) and SOCKS5;
• Rotation: external proxy IP changes according to the selected mode, by timer, new IP for every new connection, or manually by link or dashboard button;
• Bandwidth: up to 250 simultaneous TCP connections per port with 99.9% uptime;
• Targeting: city and provider level;
• Sources: verified through KYC and AML, ethically added to the allow-list;
• Pricing (prepaid, from): datacenter $0.37 / 100 MB ($3.65 / GB), residential $0.73 / 100 MB ($7.30 / GB), mobile $1.31 / 100 MB ($13.14 / GB);
• Cost control: order volume discount (2-20%, applied automatically at payment) and cumulative top-up discount (up to 25%)

Per gigabyte, the gap between types is noticeable, and that is exactly what decides where to save at high volume.
