UDP checks from our Novi Travnik node send a packet to the target port and wait for a response. This tests reachability for DNS resolvers, WireGuard/OpenVPN UDP endpoints, SIP servers, game servers, and other UDP-based services. Because UDP has no connection state, a timeout may mean the port is closed, the firewall drops UDP silently, or the application simply does not send a reply to probe packets.

Bosnia presents no unusual UDP filtering at the ISP level for commercial connections. Globalhost (AS200698) passes UDP outbound without restriction on standard hosting networks. If your UDP service responds to similar probes from Serbian or Croatian nodes but not from Bosnia, the most likely cause is a firewall rule or security group that does not cover Bosnian IP ranges — check that your ACL includes the 185.62.x.x and adjacent Globalhost prefixes if you operate explicit allowlists.

For operators running QUIC-based services, VPN infrastructure, or game servers with a Western Balkan user base, testing UDP from Bosnia alongside Serbia, Croatia, and Albania gives a full picture of regional reachability. The RTT from Novi Travnik to Belgrade is approximately 14–18 ms and to Zagreb approximately 10–14 ms, both acceptable for real-time UDP applications.

Bosnia and Herzegovina is a landlocked Balkan country whose internet infrastructure is split across two administrative entities — the Federation of BiH and Republika Srpska — each with partially separate ISP ecosystems. The national IX, BIXP (Bosnia Internet Exchange Point), is located in Sarajevo and provides domestic peering to reduce the volume of traffic that must transit through Vienna, Frankfurt, or Belgrade. Our probe node is located in Novi Travnik, hosted by Globalhost (AS200698), a regional commercial provider.

International transit from Bosnia primarily exits via Croatia (Zagreb) and Serbia (Belgrade). The Sarajevo-to-Zagreb path runs around 8–12 ms over direct links, and Sarajevo-to-Belgrade is approximately 12–16 ms. These two cities are the main upstream transit hubs for Bosnian ISPs. From Belgrade or Zagreb, onward transit to Frankfurt adds roughly 20–25 ms, making the total Sarajevo-to-Frankfurt path typically land in the 38–50 ms range depending on which upstream carrier is used.

The major ISPs in Bosnia include BH Telecom (AS8804), which operates the largest fixed-line network in the Federation, and Telekom Srpske (AS8773) serving Republika Srpska. Globalhost (AS200698) operates as a commercial hosting and transit provider with a presence primarily in central Bosnia. Other regional operators include United Media (formerly Telemach) and smaller local ISPs. Transit is predominantly sourced from RETN (AS9002), Cogent (AS174), and Telekom Srbija (AS8400).

Bosnia's IX development is limited compared to neighboring countries. BIXP in Sarajevo has fewer members than exchanges in Belgrade or Zagreb, which means a significant portion of domestic inter-ISP traffic still routes internationally before returning. This inefficiency is visible as elevated intra-country latency on some ISP pairs — two Bosnian endpoints may route through Vienna and back, adding 40–60 ms compared to what a well-peered domestic exchange would deliver. Investment in BIXP membership has grown slowly but the gap remains.

Our probe in Novi Travnik on AS200698 (Globalhost) reflects routing conditions on a mid-tier Bosnian commercial ISP. Globalhost has transit peering with several Balkan providers, giving it good regional connectivity to Serbia, Croatia, and Slovenia. For checks targeting EU-based infrastructure, expect results representative of a Balkan commercial hosting network rather than a consumer broadband connection. Consumer ISPs in Bosnia may show slightly different routing — particularly those primarily peering through BH Telecom's national backbone.
