FAQ

Frequently asked questions

Who are the main transit providers in South Korea?
viabandwidth tracks 7 IP transit and bandwidth carriers registered in South Korea, ranging from backbone operators with the largest IPv4 holdings to regional and access carriers. The top providers by network size appear first in the directory.
What is IP transit?
IP transit is a service where a network operator carries your traffic across its own network and connects it to the rest of the internet. You pay a transit provider for bandwidth capacity, and they route your packets upstream. Transit is distinct from peering, where two networks exchange traffic directly at no cost.
What service types do carriers in South Korea offer?
Carriers here advertise services such as IP transit, dedicated internet access, wavelengths, dark fiber, carrier ethernet and MPLS. Filter by service type to shortlist only the carriers that sell what you need, then compare announced route space.
How do I evaluate a transit provider?
Compare the service types they offer, their announced route space, latency to your target markets and SLA terms. A carrier profile shows a contact route only when the operator has claimed its listing and provided one; otherwise it links you to the operator site.
