Summary

SouthPrague.Net

Czechia · AI-generated

business czech small

The AS handle SOUTHPRAGUENET is held by SouthPrague.Net, z.s.

What it's used for

  • The space carries a single IPv4 block with netname CZ-SOUTHPRAGUENET-20191219 and a single IPv6 prefix, indicating a small-scale corporate or local service provider.
  • With 256 IPv4 addresses and 1 observed neighbour, the ratio suggests a limited access or internal network rather than a transit provider.

Notable

  • The registrant SouthPrague.Net, z.s. matches the AS holder, confirming consistent ownership.
  • The address inventory consists of one IPv4 /24 and one IPv6 /29, representing a minimal footprint typical of a small local operator.

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: 453 networks and 1,848 prefixes, as published 2026-11-13. 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.
