About this network

Eighteen of eighteen addresses answer, and one of them answers with the wrong address.

What it's used for

• A regional provider. Eight IPv4 prefixes and one IPv6 /32 announced from Slovakia, eleven thousand two hundred and sixty-four addresses, across two observed BGP neighbours.

Notable

• Every queried address returned a name, all but one built from the word for a host and the four octets hyphenated. One of them carries a different third number from the address it answers for, so the name and the address disagree.
• The exception is an administrative station named in words rather than numbers, with a letter dropped from the first one.
• Four blocks share a netname whose country code appears twice in a row before the brand and a date.
• One netname is the brand, a contraction for customers, and a word for residential with a letter missing.
• Three blocks list only an abuse role as registrant, with no company named on them at all.
• Eleven thousand addresses on eight announcements behind two upstreams.

Interesting

• A generated reverse zone that contains one wrong address is more revealing than a missing one. The rule produced the name from a template and somebody edited a copy by hand, leaving a name that resolves to a block it does not belong to.
• Two misspellings in two different netnames, from the same holder, suggest the fields were typed rather than generated, and that nothing has read them back since.
