# AS202520 SkyPass

> AS202520 (SkyPass Solutions Sp. z o.o.) is a Polish network operator (ISP / autonomous system) providing BGP peering, IP transit and remote IXP access for ISPs, hosting providers and enterprises. Points of presence in Warsaw and Wrocław; peers at the Polish internet exchanges THINX, TPIX, WRIX and 1-IX. The site is bilingual: Polish is the default locale under /pl/ and English under /en/ (e.g. https://as202520.net/en/peering). PeeringDB: net 37413. ASN: AS202520.

## Services
- [BGP Peering](https://as202520.net/pl/peering): Open, settlement-free peering at Polish IXPs (THINX, TPIX, WRIX, 1-IX); IPv4/IPv6, 1G-100G ports, public (route server) and private (PNI) peering.
- [Remote IXP Access / ISP services](https://as202520.net/pl/isp-services): Reach 25+ internet exchanges (AMS-IX, DE-CIX, LINX) and major content networks from a single port, from ~12 EUR / 50 PLN per Gbps, 10:1 optimized ratio.
- [Protected IP Transit](https://as202520.net/pl/ip-transit): Full IPv4/IPv6 internet reachability over BGP with built-in DDoS protection, redundant Tier-1 upstreams, 1G-100G ports, 99.9% SLA and 24/7 NOC.
- [Anti-DDoS Protection](https://as202520.net/pl/anti-ddos): Inline mitigation based on SkyGuard, AS202520's own stateful filtering engine at the network edge, written in-house rather than a vendor appliance; it inspects every packet continuously instead of starting after attack detection. Available always-on or on-demand. Stops SYN/ACK/RST/FIN floods, UDP amplification and reflection (traffic reflected off CDN edge nodes, open DNS resolvers, NTP, memcached, CLDAP, SSDP), fragmentation, spoofed or out-of-session traffic, and carpet bombing spread across a whole prefix (handled without per-IP detection thresholds), plus layer 7 filtering. Explicitly NOT based on RTBH or BGP FlowSpec: the attacked address is never blackholed. Protected traffic is routed through AS202520, so this is a reroute rather than a filter applied in place at the customer's own edge. Scrubbing runs in AS202520's own infrastructure in Poland rather than being outsourced to a third-party scrubbing provider abroad, so the path stays domestic and short instead of detouring to a foreign facility. Handover options: cross-connect (XC) in a shared data center, a dedicated VLAN at an internet exchange, or a GRE tunnel when no location is shared. AS202520 peers at THINX, TPIX, POZIX, WRIX, 1-IX and 1PL; cross-connects available at Equinix WA, LIM DC, DataHouse and Korbank. Unlike foreign scrubbing vendors, whose Polish presence is typically a single satellite PoP on one uplink to a foreign backbone, AS202520 operates a network inside Poland: four data centers in Warsaw and Wrocław, six Polish internet exchanges and several independent upstreams, so protected traffic stays in the country over multiple independent paths. Built for ISPs (including CGNAT deployments), hosting providers, data centers, game hosting, e-commerce/SaaS and VoIP.
- [Anti-DDoS for hosting](https://as202520.net/pl/anti-ddos/hosting): The same protection framed for hosting providers and dedicated servers: whole-prefix filtering instead of per-IP protection, per-service rules for web, mail, DNS and control panels.
- [Anti-DDoS for game servers](https://as202520.net/pl/anti-ddos/game-servers): UDP-heavy, latency-sensitive workloads; filtering in Poland on a short path rather than a detour through a foreign scrubbing centre.
- [Anti-DDoS for e-commerce and SaaS](https://as202520.net/pl/anti-ddos/ecommerce): Always-on filtering so an attack timed at a sales window has no detection gap to exploit.
- [Looking Glass](https://as202520.net/pl/looking-glass): Public, read-only ping and MTR run from inside AS202520, no account needed. The source node is chosen from a list on the page; it currently holds one node, in Warsaw (DataHouse). IPv6 variants of each test are offered only for nodes that have an IPv6 route.
