Summary

ISP Alliance a.s.

Czechia · AI-generated

isp residential czech alliance

The AS handle is COMTEX and the holder is ISP Alliance a.s.

What it's used for

  • The space carries residential and small business internet access, evidenced by the netname CZ-GRAPESC-20160606 and registrant GRAPESC; ISP Alliance a.s..
  • The AS announces 1024 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for local telecommunications providers operating under the ISP Alliance platform in the Czech market.

Notable

  • The registrant GRAPESC; ISP Alliance a.s. aligns with the announcer, confirming the space is held by the alliance entity.
  • ISP Alliance a.s. is an investment project created in 2012 where several local Czech telecommunications providers joined forces to compete in the market.
  • The address inventory is a single /22 block, consistent with a small, focused regional operation.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
