About this network

DGNET is operated by FIBO SA.

What it's used for

• The address space carries residential and business access traffic, evidenced by reverse DNS entries like 91-233-113-0.dg-net.pl and netnames such as PL-DGNET and DG-NET-PL.
• The AS announces 13,824 IPv4 addresses across 24 prefixes and maintains 24 observed routing neighbours, a ratio consistent with an access provider rather than a transit hub.
• As a cable and DSL ISP, the traffic consists of subscriber eyeballs, home broadband connections, and small business internet access.

Notable

• Registrants for the majority of prefixes are FIBO SA, matching the AS holder, while other prefixes are registered to OF.PL SP. Z O.O., RWD PROSPECT sp.z o.o., and Marcin Poloczek.
• The inventory includes prefixes with netnames referencing other entities, such as PL-OPTOMEDIAPOLSKA-20181127 and UK-ILUME-20190423, indicating a mixed or acquired address estate.
• The address inventory is finely subdivided into /22, /23, and /24 blocks, typical of an ISP managing distinct customer segments or legacy allocations.
