Summary
Allo Communications
isp telecom infrastructure
Three date formats in the netnames, one of them a season.
What it's used for
- A fibre provider's network. Thirty-nine IPv4 prefixes and one large IPv6 allocation announced from the United States, over three hundred thousand addresses, with thirty-four observed BGP neighbours.
Notable
- The netnames date themselves three incompatible ways:
ALLO-2020AUG05-140-228-128-0spells the month,ALLO-20200825-01runs the digits together with a counter, andALLO-SUMMER-2026gives a season and a year. - Other blocks use
ACL-99, an initialism with a counter, andALLO-NETBLK-72-8-64-0, the address written into the name. - Eight of eighteen sampled addresses answered, in a five-label form such as
72-8-111-254.hst01-oa01.hst.ne.allofiber.net: the address, a device and port code, a site code, a two-letter state and the domain. - One answering address puts a different two-letter state in that position, so the reverse names place one site outside the rest of the footprint.
- One registry lookup failed, so that block's ownership is unknown rather than absent.
Interesting
- The three date conventions are the find. All three come from the same holder and encode the same kind of fact, so a tool sorting this operator's blocks by the dates in their names has to parse a spelled month, a compact number and a season, and the season has no day at all.
- Naming the site and state in reverse DNS maps the network's footprint for anyone who reads it.

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
