YandexSpravBot
YandexSpravBot is a Yandex crawler whose documented purpose is a single phrase, Yandex Business robot. It honors robots.txt under the YandexSpravBot token and takes general rules into account. Site owners verify it by reverse and forward DNS against yandex.ru, yandex.net or yandex.com, or with the Yandex Webmaster IP check tool; Yandex publishes no IP range file.
Mozilla/5.0 (compatible; YandexSpravBot/1.0; +http://yandex.com/bots)What YandexSpravBot does
Log entries show the user agent Mozilla/5.0 (compatible; YandexSpravBot/1.0; +http://yandex.com/bots). The name and the link to Yandex's bot page identify it. Yandex's robot documentation describes it as the Yandex Business robot, and the entry records no further description of which pages it requests or what Yandex does with them. The purpose category for this entry is therefore other, because none of the more specific categories can be supported from the phrase Yandex uses.
Yandex states that YandexSpravBot honors rules addressed to its own token and takes general robots.txt rules into account. A Disallow under User-agent: YandexSpravBot stops it, and a rule for all user agents applies to it as well. What blocking changes for the site is hard to state, because the documented purpose goes no further than the three-word name. Site owners who decide on blocks by purpose have no documented basis either way here, and those who prefer a narrow rule can address this token alone rather than writing a rule that covers every Yandex robot.
Verification follows the method Yandex documents for this robot. Reverse-resolve the requesting IP, confirm the hostname ends in yandex.ru, yandex.net or yandex.com, then forward-resolve that hostname and confirm it returns the same IP. Yandex Webmaster also has an IP address check tool that performs the check for you. Yandex publishes no IP range file, so there is no list to load into a firewall; the DNS pair or the tool are the only documented options, and a matching user agent string on its own does not confirm the request came from Yandex.
Operator note. It takes into account the general rules in robots.txt.
Controlling YandexSpravBot with robots.txt
Use the token YandexSpravBot in robots.txt. Yandex documents that YandexSpravBot honors robots.txt directives.
User-agent: YandexSpravBot
Disallow: /User-agent: YandexSpravBot
Allow: /Verifying a request is really YandexSpravBot
Anyone can put YandexSpravBot in a User-Agent header. Reverse DNS lookup on the requesting IP must return a host ending in yandex.ru, yandex.net or yandex.com, and a forward DNS lookup of that host must return the same IP. Yandex Webmaster also provides an IP address check tool.
host <request-ip>
# expect a hostname ending in yandex.ru, yandex.net, yandex.com
host <that-hostname>
# expect it to resolve back to <request-ip>Common questions
Should I block YandexSpravBot?
Yandex documents the robot only as the Yandex Business robot, so there is no stated purpose to weigh a block against. If you block it, add a Disallow under the YandexSpravBot token; Yandex says the robot honors that and also takes general robots.txt rules into account. Without a documented purpose, the decision comes down to whether you want an unexplained Yandex robot fetching your pages.
How do I verify YandexSpravBot?
Reverse DNS the requesting IP and check that the hostname ends in yandex.ru, yandex.net or yandex.com, then forward-resolve that hostname and confirm it returns the same IP. Yandex Webmaster also has an IP address check tool. Yandex does not publish an IP range file for this robot.
What is YandexSpravBot for?
Yandex's documentation says only that it is the Yandex Business robot. It does not describe what the robot collects or how the data is used, and this registry adds nothing beyond that description. The user agent it sends is Mozilla/5.0 (compatible; YandexSpravBot/1.0; +http://yandex.com/bots).

This registry documents how operators describe their own bots so site owners can identify and control them. It does not publish third-party IP lists or guess at undocumented behaviour. To see how your own site responds to automated visitors, the bot detection scanner reads a URL's live response and names the protection it finds.
