Summary

ISP Alliance

Czechia · AI-generated

isp residential czech

ATLELEKTRO is operated by ISP Alliance a.s.

What it's used for

  • The address space carries static residential or business customer endpoints, evidenced by the reverse DNS record u46-255-13-254.static.atlelektro.cz and the netname CZ-GRAPESC-20101223.
  • The AS announces 2048 IPv4 addresses within a single prefix (46.255.8.0/21) and maintains 1 observed neighbour, a ratio characteristic of an access network providing last-mile connectivity rather than transit.
  • Traffic from this AS consists of end-user internet access for subscribers in Czechia, consistent with the operator's role as a local internet service provider.

Notable

  • The RDAP registrant for the announced prefix is listed as GRAPESC; ISP Alliance a.s.; ISPalliance Abuse, which aligns with the AS holder identity.
  • The address inventory is compact, consisting of a single contiguous /21 block with no IPv6 prefixes announced.

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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
