Unclassified RIPE
Summary
NBG Securities
finance business enterprise
A netname written in mixed case, where nearly every other netname in this range shouts.
What it's used for
- A securities firm's network. One IPv4
/24announced from Greece, no IPv6, two hundred and fifty-six addresses, across two observed BGP neighbours.
Notable
- The netname is a six-letter contraction with a capital in the middle and lower-case letters elsewhere, so it reads as a brand rather than as a database key.
- The AS handle is that same contraction in full capitals, so the two fields hold the same word in two cases.
- The registrants are the parent bank's initials with a legal form, and the same initials with the three letters for a network operations centre.
- Neither field contains the word for securities that appears in the company's registered name.
- Two hundred and fifty-six addresses are announced as one route, the smallest that can be.
- The routing archive has carried this number since the earliest data it holds.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- The registry stores netnames case-sensitively and almost nobody uses that. Capitals became the convention because early records were typed on systems that had nothing else, and the habit outlived the constraint by decades.
- A brokerage arm holding its own number while its contacts point at the parent bank is the usual arrangement: the trading systems need addresses that survive a change of provider, and the bank's network team runs them.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
