Hosting ARIN Content
Summary
Tiggee
infrastructure hosting business
Five brands share one network: the handle, the holder, two reverse-DNS domains, and a fifth on three blocks.
What it's used for
- An anycast DNS network. Thirty-three IPv4 prefixes and two hundred and three IPv6 prefixes announced from the United States, twenty-one thousand two hundred and forty-eight addresses, through two hundred and forty-one observed BGP neighbours.
Notable
- The AS handle is a certificate authority's brand. The holder is a differently named company, and the two share no other field.
- Most netnames are the holder's brand, sometimes with a country code, a city code and a numeral one, sometimes with a two-letter region marking which registry issued the block.
- One puts the country first, runs the company name and a numeral together, and stamps the issue date on the end.
- Three blocks belong to a fifth company entirely, all under one netname of three letters and a four-digit number.
- Two list an incident response team as a registrant object, beside the company written twice in different capitalisation.
- Seventeen of eighteen queried addresses answered across four domains: two consumer DNS brands, the holder's systems domain, and one name-server name.
Interesting
- Two hundred and forty-one neighbours on twenty-one thousand addresses is the signature of anycast: the same addresses announced from many places at once, so the count stays small.
- Two redirection domains under different brands in one record is acquisition residue. Each brand kept its zone; the addresses were pooled underneath.
- A date in a netname records when the block was issued: the one fact here nobody can revise.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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 1,768 prefixes, as published 2026-10-12. 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.
