Summary
Dragon Internet
isp telecom hosting business
Two of the five answering addresses sit on other companies' domains.
What it's used for
- A regional provider. Six IPv4 prefixes and one IPv6
/29announced from Czechia, nineteen thousand addresses, across thirty-one observed BGP neighbours.
Notable
- Two answering addresses are named under two other companies' domains, so parts of this space are run by, or resold to, businesses trading under their own brands.
- Three answering addresses use the provider's own domain, two of them marked as address translation pools with the last two octets in the name.
- One of those octet pairs writes a zero as three digits, padded to the same width as any other value.
- Five netnames are the country code, the company and an allocation date; the sixth has the company but no date, and it belongs to the oldest block.
- Every block lists three registrants built by appending role codes to the company name.
- Eighteen addresses were queried for reverse DNS and five returned a name.
Interesting
- Other brands in the reverse names are the clearest sign of wholesale. The customers are visible because they wanted to be, having put their own names on their own addresses.
- Naming address translation pools tells anyone reading logs that traffic from those addresses is shared between many subscribers, which is genuinely useful and rarely published.
- A netname without a date is almost always the first one. It was created before the convention existed and never brought into line.

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: 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.
