Summary
ABC Virtual Communications, Inc.
business telecom isp
The company writes its own name two different ways on two of its own blocks.
What it's used for
- A communications company's network. Three IPv4 prefixes announced from the United States, no sixth-version space, seven hundred and sixty-eight addresses, through one observed BGP neighbour.
Notable
- The AS handle is four letters from the holder's name followed by the autonomous system number itself, run together with no separator.
- Two blocks are the holder's own, under netnames of those four letters and the first part of each block's address.
- On one of them the registrant is in full capitals with the corporate form abbreviated and no full stop; on the other it is in mixed case with the stop present.
- The third block belongs to a carrier, and its netname stacks four things: the carrier's name, the word legacy, the name of a carrier it absorbed, and an address that is not this block's own.
- Nine addresses were queried for reverse DNS and none returned a name.
Interesting
- A handle carrying its own autonomous system number is redundant by definition, but it makes the label unique without needing a longer name, which is why small holders do it.
- Two spellings of one company on two blocks means two registrations typed at two times by two people. Nothing compares registrant strings, so the drift is permanent and invisible.
- The carrier's netname names the parent range rather than the block, so it describes where the space came from instead of what it is.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
