isp residential cable dsl

The AS handle RFC-INTERNET is held by RFC Internet Sp. z o.o.

What it's used for

  • The address space carries residential and business access traffic, evidenced by netnames such as AWACOM-NET, NET2B-NET, and BYDMAN-CUSTOMER, and reverse DNS entries like static-46-238-245-254.awacom.net.
  • The AS announces 16,384 IPv4 addresses across 14 prefixes and maintains 13 observed neighbours, a ratio consistent with a regional access provider rather than a transit carrier.
  • Traffic from this AS consists of subscriber eyeballs and small business endpoints served via cable and DSL infrastructure in the Bydgoszcz region of Poland.

Notable

  • Registrants for the majority of prefixes are RFC.PL or RFC Hostmaster, aligning with the announcer, while one prefix (94.101.16.0/20) is registered to Politechnika Bydgoska im. Jana i Jedrzeja Sniadeckich.
  • The address inventory is fragmented into multiple /22 and /23 blocks, reflecting site-by-site or technology-specific segmentation within the corporate estate.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 443 networks and 1,784 prefixes, as published 2026-10-19. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
