Summary

Vodafone Czech Republic

Czechia · AI-generated

telecom isp mobile

Over a million addresses, and every single block still named after the mobile brand that was bought.

What it's used for

  • A national mobile and fixed operator. Forty-six IPv4 prefixes and thirteen IPv6 prefixes announced from Czechia, one million two hundred and ten thousand three hundred and sixty-eight addresses, across one hundred and fifteen observed BGP neighbours.

Notable

  • Every netname is the country code, the absorbed mobile brand, and a date. Not one block carries the current brand.
  • The second registrant on all of them is that same old brand followed by three letters for a local internet registry, so the registry membership itself is still filed under it.
  • The dates run across seven years, and the largest blocks are the oldest: the operator was handed very large allocations early and kept adding.
  • All eighteen queried addresses answered. Most are two letters, the four octets hyphenated, and a subdomain for the backbone; one is marked as fixed instead, and one sits on a different subdomain of the same domain.
  • Customer addresses use a separate form entirely: a contraction for customer, sometimes with a city code, and only the last two numbers of the address.

Interesting

  • Reverse names built from only half the address work because the other half is implied by the zone. It saves nothing operationally and quietly makes the names ambiguous when read out of context.
  • Thirteen separate IPv6 prefixes rather than one is the mark of a group that has absorbed several registry memberships and never consolidated them.

Reputation

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
