AS56371 announces 1 IPv4 prefixes covering 256 addresses and 0 IPv6 prefixes.

About this network

The AS handle CRBG-AS is held by Creditreform Bulgaria EOOD.

What it's used for

• The space carries corporate infrastructure, evidenced by the netname CREDITREFORM and registrant A1 Bulgaria EAD Abuse associated with the single announced prefix.
• The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
• Traffic from this AS consists of office workers and business endpoints for Creditreform Bulgaria, a debt collection and management agency established in 1993.

Notable

• The registrant A1 Bulgaria EAD Abuse differs from the AS holder, suggesting the address space is leased from or managed in coordination with A1 Bulgaria, a major Bulgarian telecommunications operator.
• The address inventory is minimal, consisting of a single /24 block, which fits the profile of a specific corporate site or internal estate rather than a broad service network.
